Answer 1

Answer: 8.4

Step-by-step explanation:

1985 milk price: $2.26

2005 milk price: $2.45

2.45-2.26=0.19/2.26= 0.0840708 x 100 = 8.40707965 round to 8.4

You will minus the 2005 price by the 1985 price, and then divide by 1985 price. After that step, you will multiply by 100 and round to the nearest tenth.
