Answer:


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.
