Finley's pumpkin had a mass of 6.5 kilograms (kg) before he carved it. after carving it, the pumpkin had a mass of 3.9kg. what was the percent decrease in the mass of the pumpkin?

Its mass decreased 40%

6.5 - 3.9 = 2.6

2.6 / 6.5 = 0.4

0.4 = 40%

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
