Part B
Write an expression for how much the rosebush will cost if the 10% discount is applied first and
the coupon is applied second.
Part
Which order will save Marina more money? Explain your reasoning.

Answers

Answer:

Part A: 0.9d - 4.5

Part B: 0.9d - 5

Part C: Order that will save Marina money is "discount applied first, then coupon"

Step-by-step explanation:

Part A

The rosebush costs "d" dollars

Coupon = $5 OFF

Discount = 10%

We want to find cost of rosebush when COUPON APPLIED 1st and DISCOUNT APPLIED 2nd.

Cost = d

Coupon Applied Cost = (d - 5)

Discount Applied Cost = 10% off means 100 - 10 = 90% of the price remains, that is 90/100 = 0.9 times the price, so:

0.9(d - 5) = 0.9d - 4.5

Part B

When we apply 10% discount to the initial price of "d", we get 90% of the price remaining.

So, price would be:

Normal Price = d

Discount Price = 0.9d

Now, coupon applied of $5, we get:

0.9d - 5

Part C

We have two expressions, let the original price, d, be 100, so

Part A price would be 0.9d - 4.5 = 0.9(100) - 4.5 = 85.5

Part B price would be 0.9d - 5 = 0.9(100) - 5 = 85

So, Marina will save up money going on the 2nd option.

Order that will save Marina money is "discount applied first, then coupon"

What is the value of 2x{6+[12/(3+1)}-1

Answers

The value of an expression is calculated by simplifying the expression.

The value of the expression is 17

The expression is given as:

$\mathbf{2 * \{6+[12 / (3+1)\}-1}$

Simplify 3 + 1

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{6+[12 / 4\}-1}$

Divide

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{6+[3\}-1}$

Remove square bracket

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{6+3\}-1}$

Add

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{9\}-1}$

Remove curly bracket

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * 9-1}$

Multiply

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 18-1}$

Subtract

$\mathbf{2 * \{6+[12 / (3+1)\}-1 = 17}$

Hence, the value of the expression is 17

72. first multiply 1 1/2 by 2 and you get 3 for 6 dozen, then add 1/2 and you get 3 and 1/2 for 7 dozen.
73. 3+2 is 5, and 2 is 66% of 3, so it is a 66% increase
74. 495 X .07 is 34.65, so she gets $34.65 dollars
