A cashier offers Nathan an opportunity to save twenty-five percent on his purchase. The original cost is eighty-three dollars. Estimate what his savings would be, then calculate the actual savings.

Question

stamp · Answer

25% of $83 = savings

Estimate.

$83 ~ $80

25% of $83 ~ 25% of 80 = 20

Find actual savings.

25% of $83 = 0.25 of 83

0.25 of 83 = 0.25 (83)

0.25 (83) = 83/4

Simplify.

83/4 = 20 3/4 

20 3/4 = 20.75

$20.75 saved
