Question

Notebooks cost $ 1.20 each. This weekend they will be on sale for $ 0.80. What percentage is the sale

Answer 1

if you mean what was the percentage of how much lower it got, I think about 32%. Somewhere around there

Answer 2

so sale is x% off
find how much was taken off
1.20-0.80=0.40

so find what 0.4 out of 1.20 is
0.4/1.2=4/12=1/3=33.33%


so the sale is 33.33% off
