B. 9 shirts
C. 12 shirts
D. 16 shirts

Answer 1

The answer is c: 12 shirts

Answer 2

The number of shirts that Cameron's Brother has is:

C. 12 Shirts

Explanation:

Cameron has 75% as many shirts as her brother.

let the number of shirts Cameron has be= C

let the number of shirts Cameron's brother has be= B

Then, C=9 (Given)

Since,

Cameron has 75% as many shirts as her brother.

So,

C=75/100 X B

9=75/100 X B

9X100/75=B

B=9X100/75

75/100 can be reduced to the fraction 3/4,

as 75= 25X3 and 100=25X4

Thus,

B=9X100/75

B=9X4/3

3 cancels 9 to leave 3,

Thus,

B=3X4

B=12

So,

Answer=12 Shirts

Number of shirts that Cameron's Brother has are 12
