Question

An article that is marked $500 was sold for $450 after a discount is given. Calculate the percentage discount given

Answer 1

10% discounted

Explanation:

500× X = 450

while X is the sale price

so we solve for X

(500X)÷500 = 450 ÷ 500

X = 0.9

then we turn that into percentage

0.9 × 100 = 90%

finding the discount percentage

100% - 90% = 10%
