A gift shop sells 140 wind chimes per month at $90 each. The owners estimate that for each $5 increase in price, they will sell

guapka [62]

Answer: $95

Step-by-step explanation:

Te new price will be 90 + 5x, if the price increases "x" times

The number of wind chimes sold per month will become 140 - 7x

$\begin{aligned}&\text {Revenue, } \mathrm{R}(\mathrm{x})=(90+5 \mathrm{x})(140-7 \mathrm{x}) \\&R^{\prime}(x)=5(140-7 x)-7(90+5 x) \\&R^{\prime}(x)=700-35 x-630-35 x \\&R^{\prime}(x)=70-70 x=0 \\&70 x=70 \\&x=1\end{aligned}$

Therefore, if the price becomes (90 + 5(1)) = $95 per wind chime, then the revenue will be maximum

What is the solution for -3x ≥ 36?

Montano1993 [528]

Hey there!

To solve for the solutions of your inequality, divide both sides of your inequality by -3 in order to isolate the value of x:

-3x≥36
÷-3 ÷-3

x≤12
**Note: in inequalities, if you ever divide or multiply a number that is negative, you must flip the inequality sign. In this case, because you have divided -3 from both sides, you must flip the inequality sign from ≥ to ≤.

Therefore, your solutions to your inequality would be x≤12.

Hope this helps, and have a nice day! :)
