### HideShow timer Statistics

Physicians often estimate the adult height c, in inches, of a female child by using the inequalities

$$\frac{m+f-13.2}{2} \leq c \leq \frac{m+f-2.8}{2}$$

where m represents the mother's adult height and f represents the father's adult height, both measured in incehs. If Rachel is a 5-year-old girl, what is her maximum adult height that will satisfy these inequalities?

(1) Rachel's height at age 5 is 44 inches
(2) Rachel's mother's adult height is 62 inches and Rachel's father's adult height is 71 inches

Hi

Not sure I understand what the question is asking? Are we supposed to get ONE value? Prove something correct/incorrect?

Thanks!

The max value of C is what the question is looking for..

Correct!

I put the OA in there but for some reason I can't see it.
