Answer:

3888

Step-by-step explanation:

Let Caitlyn be C and Ashley be A.

By the problem,

C=72+A

C=3A

So, 2A=72

therefore Ashley has 36 dolls

and Caitlyn has 108 dolls

and the photo of the two sisters' dolls is 3888

Answer:

3888.

Step-by-step explanation:

y = x + 72   where y = number of Caitlyns dolls and x is the number of Ashleys.

Also y = 3x

So we substitute y = 3x in the first equation to get:

3x = x + 72

2x = 72

x = 36 = total od Ashley's dolls.

So Caitlyn has 36 + 72 = 108 dolls.

Product = 108 * 36 =  3888.
