Ryan made $272 for 17 hours of work. At the same rate, how much would he make for 11 hours of work?

$176

Step-by-step explanation:

272 / 17 = 16

16 * 11 = 176

176

Step-by-step explanation:

1. 272 divided by 17 = 16

2. 16 x 11= 176

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
