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

pashok25 [27]

Given:

There is an equation given as

$y=65.18x+21.43$

fits the scatterplot of the values for stock ABC over the past month with an r-value of 0.9874.

Required:

We need to find that what will be worth at x= 32 days?

Explanation:

The equation fits the scatter plot of the values for stock ABC over past month with r-value of 0.9874 is

$y=65.18x+21.43$

to find ABC will be worth at x=32 just substitute x=32 in the given equation

$y=65.18(32)+21.43=2058.76+21.43=2107.19$

Final answer:

Therefore, $2107.19 ABC will be worth at x=32 days
