On Thursday a local shop sold a combination of 417 hamburgers and cheese burgers. The number of cheeseburgers sold was two times the number of hamburgers sold. How many burgers were sold on Thursday

Answers

Answer:

The number of hamburgers sold was 139 and the number of cheeseburgers sold was 278.

Step-by-step explanation:

Let

x -----> the numbers of hamburgers sold on Thursday

y -----> the numbers of cheeseburgers sold on Thursday

we know that

$x+y=417$ ----> equation A

$y=2x$ ----> equation B

Substitute the equation B in equation A and solve for x

$x+2x=417$

$3x=417$

$x=139$

Find the value of y

$y=2(139)=278$

therefore

The number of hamburgers sold was 139 and the number of cheeseburgers sold was 278.

25 is 32% of what number?

Answers

The value of the unknown number is 78.125.

What is the value of the unknown number?

Given the parameter in the question:

25 is 32% of what number?

Let x represent the value of the unknown number,

Translating into an equation:

32% of x = 25

Note that: 32% is the same 32/100

Hence:

32/100 × x = 25

Multiply 32 and x:

32x/100 = 25/1

Next, cross multiply:

32x × 1 = 100 × 25

32x = 100 × 25

Multiply 100 and 25

32x = 2500

Divide both sides by 32

x = 2500/32

x = 78.125

Therefore, the value of x is 78.125.

You can solve that by cross multiplication.
If 25 is 32%, then x is 100%:
25/32 = x/100
25*100 = 32*x
x = 25*100/32 = 78.125

To check the solution: 78.125*(32/100)=25

For this kind of question you just have to multiply times 100/percentage, that's what you always arrive to with the cross multiplication.
So if they asked you, 50 is 25% of what? You'd do 50*(100/25) = 200.
It's the reverse of finding the percentage of a number.
