Question

A football team runs 11 plays. There are 3 plays that result in a loss of 2 yards each and 8 plays that result in a gain of 4 yards each. To find the total yards gained, Art evaluates the expression 3(-2)+ 8(4). Bella first finds the total yards lost, 6, and the total yards gained, 32. Then she subtracts 6 from 32. Compare these two methods.
