Answer:
y=7x+5
Step-by-step explanation:
fred = 45 books
sally has 27 times more book than fred
sally = 45 X 27
= 1215 books
Take the pre-sale price.
Divide the original price by 100 and multiply it by 30.
Take this new number away from the original one.
The new number is your discounted value.
÷10=0.009.
Therefore, 0.09 is 10 times as much as 0.009.
