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

`p=18h`

or

`p=(450)/(30)\cdot 1.2\cdot h`

Explanation:

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

`(\$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=(450)/(30)\cdot 1.2\cdot h.`
