Answer:
He rented the bike for 2 hours.
Step-by-step explanation:
Since a bike costs $13 plus $5 per hour, we can write this as:
13 + 5(h)
We used "h" as the variable for hours, since we need to find how many hours he rented the bike for, that he had to pay $23.
And since Pete paid $23, we need to make the other equation equal to 23.
= 23
So the actual equation, would look like this:
13 + 5(h) = 23
Now we just solve for h in the equation:
13 + 5(h) = 23
Step 1: Multipy 5 times "h"
13 + 5h = 23
Step 2: Subtract 13 from both sides
13 + 5h - 13 = 23 - 13
Step 3: Simplify
5h = 10
Step 4: Divide both sides by 5
5h/5 = 10/5
Step 5: Simplify
h = 2
So the number of hours that Pete rented the bike for 2 hours
