Question

Need Help:

11.) Last night, the Knicks made 12 free throws. If their free throw percentage is 75%, how many free throws were attempted?

12.) Dr. Hall files 320 insurance claims every month. If 5% of those claims are rejected, how many claims are rejected? How many are accepted?​

Answer 1

11.) 16

12.) rejected: 16; accepted: 304

Explanation:

11.) The free throw percentage is the proportion of attempts that are made:

75% = made/attempts = 12/attempts

Multiplying the equation by attempts, we get

attempts·0.75 = 12

attempts = 12/0.75 = 16

The Knicks attempted 16 free throws.

___

12.)

a) The number rejected is the percentage multiplied by the number submitted:

rejected = 5%·320 = 16

b) The number accepted is the number submitted that were not rejected:

accepted = 320 - 16 = 304

Of 320 claims submitted, 16 were rejected and 304 were accepted.
