Question

A digital camera usually costs $700. This week it is on sale at a discount of 20%. What

is the sale price of the digital camera?

Answer 1

560

Explanation:

So we know that 20% goes into 100% 5 times.

700/5 will give you a clean 140, meaning 20% of the price is 140

Thus 700-140 and you get 560 dollars

If you have a calc you could also do 700 x .80 (since .80 is also equal to 80%) and get the same answer
