Question

Please please help me

Answer 1

$180

Explanation:

let pay be p and hours worked be h

Given p varies directly as h then the equation relating them is

p = kh ← k is the constant of variation

To find k use the condition p = 45 when h = 7.5, then

k =
`(p)/(h)` =
`(45)/(7.5)` = 6, thus

p = 6h ← equation of variation

When h = 30, then

p = 6 × 30 = $180

Answer 2

Answer: 180

Explanation:

divide 45 by 7.5 to get the amount of dollars earned per hour

45/7.5 = 6

6(x)= 30hours, = 6(30) = $180
