On a beach trip lucy rents a bike from wheel by the waves where they rent bikes for $12 plus $3 per hour if lucy spent $30 how many hours (h) did she ride a bike

6 hours

Step-by-step explanation:

Make an equation

Each hour costs $3, and there is a $12 cost regardless of the hours. We know that Lucy spent $30.

3h+12=30

Subtract 12 from both side s

3h=18

Divide both sides by 3

h=6

So, she rented it for 6 hours
