Julio rented a bike from raving riders' bikes. it cost $12 plus $2.20 per hour. if julio paid $23, for how many hours did he rent the bike?

To solve this problem, we can set up an equation using the variable x to represent the unknown number of hours Julio rented the bike for. We know that Julio paid 23 dollars total, so this must be one side of the equation. This should be set equal to the standard 12 dollars plus the added 2.20 multiplied by the number of hours Julio rented the bike for (represented by x). This is as follows:

23 = 12 + 2.20x

Now, we must solve this equation. To begin this process we must subtract 12 from both sides of the equation.

11 = 2.20x

Finally, we must divide both sides of the equation by 2.20 because we must cancel out the coefficient on the variable x in order to isolate it.

5 = x

Therefore, Julio rented the bike for 5 hours total.

Hope this helps!

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
