Answer 2

The price of tomatoes would be about $1.11 in the year 2000.

To solve this problem, you have to set up and solve a proportion. On the left put the CPI numbers. On the right put the tomato prices. Use x for the unknown amount in 2010.

122.8 / 181 = 0.75 / x

Cross multiply and divide and you will have about 1.11.
