Question

What is the percent of increase in the rent for Bob's apartment if it went from $560 to $616?

Answer 1

This is a two step problem. First, you need to find the difference (or increase) in the rent using subtraction.

616-560 = $56 increase

Now we need to figure what percent 56 is to the original amount (560)

We voice it like this:

56 is to 560 as x is to 100.

The equation looks like this:

56/560 - x/100

Cross multiply to cancel out the denominators.

56 x 100 = 560 x

5600 = 560 x

x = 10 percent.

Check it!

What is 10 percent of 560?

560 x .1 = $56

Was that your increase? ... yes.

10%

Step-by-step explanation:

Apply the formula for percent increase: 616-560/560 * 100 = 56/560*100=10%... ALL CREDIT GOES TO AOPS
