Question

Alexa worked 30 hours last week and earned $450. Her pay has now been increased by 20%. Which equation describes her new rate of pay, p, based on the number of hours, h, worked

Answer 1

Answer:

$p=18h$

or

$p=\dfrac{450}{30}\cdot 1.2\cdot h$

Step-by-step explanation:

If Alexa worked 30 hours last week and earned $450, then her hourly payment is

$\dfrac{\ 450}{30}=\ 15.$

Her payment has now been increased by 20%, so her hourly payment becomes

$\ 15\cdot 1.2=\ 18.$

If she worked h hours, then she earned $\ 18h.$ If her new payment is p, then

$p=18h$

or

$p=\dfrac{450}{30}\cdot 1.2\cdot h.$
