Answer: 180
Step-by-step 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
Answer:
$180
Step-by-step 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 = [tex]\frac{p}{h}[/tex] = [tex]\frac{45}{7.5}[/tex] = 6, thus
p = 6h ← equation of variation
When h = 30, then
p = 6 × 30 = $180
