Ben spent 1/6 of his money on a burger, fries, and a drink. Then he spent half of the money he had left: $5 on a magazine, $8.25
Ket [755]

The amount of money Ben had to begin with after spending 1/6 and 1/2 of it is 57 dollars.

<h3>How to find the how much money he had with an equation?</h3>

let

x = amount he had to begin with

He  spent 1/6 of his money on a burger, fries, and a drink. Therefore,

amount spent on burger, fries, and a drink = 1  / 6 x

Hence,

amount he had left = x - 1 / 6 x =6x - x /6 = 5 / 6 x

Then he spent half of the money he had left.

1  / 2(5  /6 x) = 5 + 8.25 + 10.50

5 / 12 x = 23.75

cross multiply

5x = 23.75 × 12

5x = 285

divide both sides by 5

x = 285 / 5

x = 57

Therefore, the amount of money he have to begin with is $57.

frozen [14]

Answer:

Length=44feet

Width=12feet

Step-by-step explanation:

length:width=11:3

Perimeter=56feet

Sum of ratio=11+3

Sum of ratio=14

Length=11/14 x 56

Length=(11 x 56)/14

Length=616/14

Length=44feet

Width=3/14 x 56

Width=(3 x 56)/14

Width=168/14

Width=12feet
