Question

(a) write a linear cost function representing the monthly cost ( c(x) ) for ( x ) maintenance calls. the linear cost function is ( c(x)=\boxed{34x + 650} ). part 2 of 5 (b) write a linear revenue function representing the monthly revenue ( r(x) ) for ( x ) maintenance calls. the linear revenue function is ( r(x)=\boxed{64x} ). part 3 of 5 (c) write a linear profit function representing the monthly profit ( p(x) ) for ( x ) maintenance calls. the linear profit function is ( p(x)=square ).

Explanation:

Step1: Recall profit formula

Profit = Revenue - Cost, so $P(x) = R(x) - C(x)$

Step2: Substitute given functions

$P(x) = 64x - (34x + 650)$

Step3: Simplify the expression

$P(x) = 64x - 34x - 650 = 30x - 650$

Answer:

$30x - 650$
