Answer:97.1
Step-by-step explanation:
The equation that you must use is y=15x+15
so x would be 1,2,3,4,5 and y would be 30,45,60,75,90
To express any number as a decimal, just multiply it by 100 .
Often, an easy way to do that is to move the decimal point

2.50 = <em>250%</em>

originally. Then you reduces the side lengths a so it will be

Just note that 40% is the same as 2/5.<span />
