Answer:
a is the correct answer in e2020
Step-by-step explanation:
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
3p - 1/8.
I am guessing that you would like an expression. Our expression would be: 3p - 1/8. In this expression, the 3p represents the 3 times as much as she bought in May. Since it is 1/8 less, we will subtract 1/8 from the 3p to get our expression.
