cluponka [151]

Answer:

27 calls

Step-by-step explanation:

Let T(x) represent total sales.

Then T(x) = $150 + ($2/call)x, where x is the number of calls made.

If T(x) = $204, we can solve for x, the number of calls made:

$204 = $150 + ($2/call)x, or

Simplify the expression and show work 4(3x-2)-7(x+5)

Gennadij [26K]

Answer:

5x - 43

Explanation:

Given the below expression;

$4\left(3x-2\right)-7\left(x+5\right)$

To simplify the above, we'll go ahead and use the numbers outside the parentheses to multiply the ones inside to clear the parentheses as seen below;

$\begin{gathered} 12x-8-7x-35 \\ =12x-7x-8-35 \\ =5x-43 \end{gathered}$

So the answer is 5x - 43
