Question

The Fitzgerald’s paid $3,200 to heat their home in the year 2018. By the end of year 2019, they saw the cost of heating their home rose to 3,516 for the year. Which of the following could be used to find the difference in what they paid from 2018 to 2019

Answer 1

Ok to see the difference of what they paid between those years you should look for the percentage change. To do this first you have to calculate the quotient between the 2019 value and the 2018 value: 3516/3200=1.099.

That number multiplied by 100 gives you the percentage of the rise:

1.099*100=109.875% so the price increased a 9.875%.

So the correct answer would be item A.
