The value of a car dropped from $7400 to $6800 over the last year. What percent decrease is this? |
| Answer» UTE the percent CHANGE, we FIRST need to FIND the dollar value change: $6800- $7400 = -$600. Often we will take the absolute value of this amount, which is called the absolute change: l−600l = 600. Since we are computing the DECREASE relative to the starting value, we compute this percent out of $7400: 600/7400 = 0.081= 8.1% decrease. This is called a relative change. | |
