Answer:
[tex]p=18h[/tex]
or
[tex]p=\dfrac{450}{30}\cdot 1.2\cdot h[/tex]
Step-by-step explanation:
If Alexa worked 30 hours last week and earned $450, then her hourly payment is
[tex]\dfrac{\$450}{30}=\$15.[/tex]
Her payment has now been increased by 20%, so her hourly payment becomes
[tex]\$15\cdot 1.2=\$18.[/tex]
If she worked h hours, then she earned [tex]\$18h.[/tex] If her new payment is p, then
[tex]p=18h[/tex]
or
[tex]p=\dfrac{450}{30}\cdot 1.2\cdot h.[/tex]
