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]
