Question

PLS HELP IF U CAN !! Tell whether each percent change is an increase or

decrease. Then find the percent change.
11. original amount: $5000
new amount: $6500
12. original amount: 150 lb
new amount: 135 lb

Answer 1

Problem 11

A = old amount = 5000

B = new amount = 6500

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (6500-5000)/5000 ] * 100%

C = (1500/5000) * 100%

C = 0.3*100%

C = 30%

We have a percent increase because C is positive.

Answer: 30% increase

===========================================================

Problem 12

A = old amount = 150

B = new amount = 135

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (135-150)/150 ] * 100%

C = ( -15/150 ) * 100%

C = -0.10*100%

C = -10%

The negative C value indicates a percent decrease.

Answer: 10% decrease
