Need :

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?

11.)  16

12.)  rejected: 16; accepted: 304

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.

final answer is : )
