Question

Margo’s dog, named Todd, weighed 120 pounds last year. She now weighs 180 pounds. What is the percent of change

Answer 1

Explanation:

`\Delta \%=100\left((final-initial)/(initial)\right)\\ \\ \Delta \%=100\left((180-120)/(120)\right)\\ \\ \Delta \%=100\left((60)/(120)\right)=50\%`

Answer 2

50%

Explanation:

the increase is 60 so divide that by the original number; 60/120=0.5

now we have to change the decimal to a percent. multiply by 100 to do that and we get 50%.
