Step-by-step explanation:
Subtract the discount from 100 to get the percentage of the original price.
Multiply the final price by 100.
Divide by the percentage in Step One
2 peach pies = 10 cups 10 divided by 2(peach pies) = 5 cups per pie.

7√7
using the ' rule of radicals '
• √a × √b ⇔ √ab
simplifying the radicals
√28 = √(4 × 7 ) = √4 × √7 = 2√7
√63 = √(9 × 7) =√9 × √7 = 3√7
√112 = √(16 × 7 ) = √16 × √7 = 4√7
substituting into the expression
3(2√7) - 5(3√7) + 4(4√7) = 6√7 - 15√7 + 16√7 = 7√7
