Answer:
Sales price = $5.13
The total price paid (with discount): $0.57
Step-by-step explanation: To find the sales price, you would recall the formula:
Whole number * part percent / 100
Let's plug in the numbers to the formula:
5.70 * 90 / 100
5.70 * 90 = 513
513 / 100 = 5.13
If you wanted to find the total price the person pays AFTER the discount, you subtract 5.13 from 5.70.
So, 5.70 - 5.13 = $0.57
I hope this helps!
