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