Question

8. Johnny had $20. He went to the store and

bought $12 worth of candy, chips and soda. What
is the percent of change in Johnny's money?
(7.RP.3)

Answer 1

Explanation:

%change=100(final-initial)/(initial)

final=20-12=8 and initial=20 so

%change=100(8-20)/20

%change=100(-12)/20

%change=-1200/20

%change= -60%
