Answer:

We can conclude that -

  • The percentage by which the selling price will decrease is 16%. The price will have to increase by 16% to return back to the original price.
  • The price will have to increase by 16% to return back to the original price.

What is Selling price?

The price at which a specific commodity is sold is known as the selling price.

Given is that the selling price of a house dropped from $250,000 to $210,000 over a period of 5 years.

A -

The percentage by which the selling price will decrease is -

%decrease = (250000 - 210000)/250000  x  100

%decrease = 40000/250000  x  100

%decrease = 4/25 x 100

%decrease = 4 x 4

%decrease = 16%

B -

The price will have to increase by 16% to return back to the original price.

Therefore, we can conclude that -

  • The percentage by which the selling price will decrease is 16%. The price will have to increase by 16% to return back to the original price.
  • The price will have to increase by 16% to return back to the original price.

A climbing gym charges $10 to climb each day.A pair. of climbing charges shoes cost $84.It costs $169 to buy 6 days of climbing,one pair of climbing shoes,and one harness.How much does a harness cost? WRITE AN EQUATION FOR EACH PROBLEM. USE A VARIABLE FOR THE UNKNOWN NUMBER. SOLVE.

Answers

The equation representing the given problem is:

6x   +  y  +  z  =   169

A harness costs $25

Let the charge for 1 day of climbing be represented by x

x  =  $10

Let the price of 1 pair of climbing shoes be represented by y

y  =  $84

Let the price of 1 harness be represented by z

It costs $169 to buy 6 days of climbing, one pair of climbing shoes, and one harness

Total cost  =  $169

The equation representing the given scenario is:

6x   +  y  +  z  =   169

To find the value of z, substitute x = 10 and y = 84 into the equation

6(10)  +  84  +  z  =  169

60  +  84  +  z  =  169

144  +  z  =  169

z  =  169  -  144

z   =  25

Therefore, a harness costs $25

The correct answer is:

The harness is $25.

Explanation:

Let x represent the cost of the harness.

Each day of climbing is $10. This means 6 days of climbing is represented with 10(6). The shoes are $84. This makes our expression 10(6)+84. Adding the harness, x, to that, our total comes to $169. This gives us the equation

10(6)+84+x = 169

Simplifying the left hand side, we have

60+84+x = 169

Combining like terms, we have

144+x = 169

Subtract 144 from each side:

144+x-144 = 169-144

x = 25

The harness is $25.

Frances used small, medium, and large cups to serve punch. She used 243 medium cups. She used 79 more medium cups than a large cups. She used 56 more small cups than large cups. How many small cups did Frances use to serve punch?

Answers

The required, Frances uses 220 small cups to serve punch.

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Frances used small, medium, and large cups to serve punch.
Let number of small and large cups be x and y,
According to the question,
She used 79 more medium cups than a large cups.

y = 243 - 79
y = 164


She used 56 more small cups than large cups.
x = 164 + 56

x = 220

Thus, the required, Frances uses 220 small cups to serve punch.

Mary has 50 earring boxes. The boxes measure 1 inch on each side. How many rectangular prisms, each with different-sized base, could Mary make by stacking all the earring boxes?

Answers

Since each earring box has a side of 1 inch, that means each one has a volume of 1 cu. inch. Thus, 50 cubes combined will have a volume of 50 cu. inches. That means, that the prism must have a volume of 50 cu. inches. Since for prism, the volume is L(W)(H), we can list down the possible trios that will have a product of 50. Note that 50 = 1 x 2 x 5 x 5 and hence, we can group these and come up with the following list of factor: {1, 2, 25}, {1, 10, 5}, {2, 5, 5} Therefore, there are 3 possible prisms that can be formed using the cubes. The answer is 3.
