Which sentence matches the mathematical equation? p-0.40p=0.60p

a. Decreased by 40 is the same as multiply by 60

b. Decreased by 40 is the same as increase by 60

c. Decreased by 40% is the same as multiply by 60%

d. Decreased by 40% is the same as increased by 60%

P-0.40p = 0.60p

C. Decrease by 40% is the same as multiply by 60%.

Assume that p = 10

10 - 0.40 (10) = 0.60 (10)

10 - 4 = 6

6 = 6

Based on the above assumption. 40% of 10 is 4; and 60% of 10 is 6. So, 10 less 4 (40% of 10) is equal to 6 (60% of 10).

Percentage is used because 0.40 and 0.60 will be multiplied with 100% to get the equivalent percentage 0.40 x 100% = 40%; 0.60 x 100% = 60%
