First one

 

(r - c)(4)  =  r(4) - c(4)  =

 

[ 4^2 + 6(4) + 10 ] - [ 4^2 - 4(4) + 5 ]  = 

 

[ 16 + 24 + 10 ] - [ 16 - 16 + 5 [ =

 

50 - 5  =

 

45

 

This means that the store will have a profit of $4500 after 4 months

Second one.....a little tricky to interpret !!!

 

(p*c)(2)  =  p(2) *c(2)  =

 

[ 80 - 2(2) ]  * [ 50 + 5(2) ] =

 

[ 76] * [ 60 ]  =

 

 

$4560

 

The "2"  represents the number of $5 ncreases above $50  = 2*5 + 50 = $60 per customer

 

So...the company can expect $4560 in revenue when they charge $60 per customer
