Answer:

(0, 6 )

Step-by-step explanation:

Given the 2 equations

- 6y + 11x = - 36 → (1)

- 4y + 7x = - 24 → (2)

Multiplying (1) by 4 and (2) by - 6 and adding the result will eliminate y

- 24y + 44x = - 144 → (3)

24y - 42x = 144 → (4)

Add (3) and (4) term by term

2x = 0 ⇒ x = 0

Substitute x = 0 in either of the 2 equations and solve for y

Substituting in (1)

- 6y + 11(0) = - 36, that is

- 6y = - 36 ( divide both sides by - 6 )

y = 6

Solution is (0, 6 )

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
