Answer: she still has to cut off 19/16 inches.
Step-by-step explanation:
Olivia wants to cut 3 3/4 inches from a piece of string. Converting 3 3/4 inches to improper fraction, it becomes 15/4 inches.
She has already cut off 2 9/16 inches from the piece of string. Converting 2 9/16 inches to improper fraction, it becomes 41/16 inches.
Therefore, the length of string that is left for her to cut off would be
15/4 - 41/16 = (60 - 41)/16
= 19/16 inches
Let's find out how much is the 30% discount to 47.50 dollars.
=> 30% = 30% /100 = .30
Now, multiply this decimal to the given amount in dollars.
=> 47.50 dollars * .30 = 14.25 dollars
Thus the 30% discount of 47.50 dollars is 14.25 dollars.
