Luisa earns money mowing her neighbors' lawns.

Irina-Kira [14]

Answer:

$p(x)=16x-25$

C is the correct option.

Step-by-step explanation:

We have been given that

$r(x)=20x\\c(x)=4x+25$

The profit is the difference of revenue and cost function.

Mathematically, we can write profit function as

$p(x)=(r-c)x$

We know that $(f-g)(x)=f(x)-g(x)$ . Thus, we have

$p(x)=r(x)-c(x)$

Plugging, the r(x) and c(x) functions

$p(x)=20x-(4x+25)$

Distribute negative over the parenthesis

$p(x)=20x-4x-25$

Combine the like terms. 20x-4x = 16x

$p(x)=16x-25$

C is the correct option.
