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

The first inverse operation you would use to solve the equation 2+5x= -8 for x is subtraction. true or false?
jok3333 [9.3K]

Answer:

It would be True

Step-by-step explanation:

2+5x = -8

SUBTACT 2 on both sides and it would look like this:

5x = -8 - (2)

5X= -10

then DIVIDE 5 both side to get "X" ALONE,

x= -10/5

then divide -10 with 5

equal to:

x = -2

Solve each equation. Check your answer<br>r/238=8
ozzi
You have to get r by itself on one side. Multiply both sides by 238 to cancel it out of the denominator on the left side.

You are left with r = 8 × 238 or r = 1904.

To check, plug 1904 back into the equation.

1904 ÷ 238 = 8
8 = 8 (True)
