Bh + hr = 25
you can factor out an h from the left side of your equation:
h(b + r) = 25 ... divide both sides by h
b + r = (25/h) ... subtract r
b = (25/h) - r

Answer:
$74.50
Step-by-step explanation:
Using their given equation, y = 2.50x + 12, we can substitute 25 for x in order to solve it.
y = 2.50x + 12
y = 2.50(25) + 12
y = 62.50 + 12
y = 74.50
Therefore, Marty pays $74.50 for the total price if he rents 25 movies.
