Question

Gina wants to ride the waves flagship pier in Galveston so she rents a surfboard for 5$ per hour plus initial payment of 20$ for how many hours can Gina rent a surfboard if she has 90$?

Answer 1

You can put this in a linear equation where 20 is the b value and 5 is the m. The equation will be.
y=5x+20. Substitute 90 for y and solve for x

90=5x+20
70=5x
14=x

Gina can rent the surfboard for 14 hours
