11.) A manager at a jewelry store buys jewelry at a whole sale cost of "x" . To set a price on the item in the store she first adds $25 and she calls this function "a(x)" . Then, she increases by 80% and calls this combined price increase "p(a(x))" . Create a function model that expresses the overall increase in price.

a(x)   = x + 25

 

pa(x)  = (x + 25) (1.80)  =  1.80x + 45

 

The overall increase in price  [above cost ]  = 

 

pa(x)  - x   =    

 

1.80x + 45  - x  =

 

.80x + 45

I like how you solved the equation but from what it looks like I'm just confused because it first said "a(x) and then it said "p(a(x))" . What equation are you referring to CPhill?
