Answer:

The cost of 1 gallon is $2.5

Step-by-step explanation:

Given

Cost of 14 gallons = $35

Required

Determine the cost of 1 gallon

From the given parameters, we have:

$14\ gallons = \$35$

Divide both sides by 14

$\frac{14\ gallons}{14} = \frac{\$35}{14}$

$1\ gallon = \frac{\$35}{14}$

$1\ gallon = \$2.5$

Hence,

<em>The cost of 1 gallon is $2.5</em>

1) Debbie has $93 saved up to buy a PS4 on Black Friday. On Black Friday the PS4 will cost $150 dollars, if Debbie babysits and earn two dollars everyday she babysits, how many days left does she have until she can buy the PS4?

2n+93=150

2n=150-93

2n=57

n= $\frac{57}{2}$

2) What does P equal? P stands for the amount of apples needed for a pie sale. We also need to find Q, which is how much peaches we'll need as well, because it is a peach and apple pie sale.

$\frac{p}{10}= \frac{7}{q}$

$p=\frac{7}{q} *10$

$p=\frac{70}{q}$

-----------------------------------------

$\frac{p}{10}= \frac{7}{q}$

$\frac{p}{10}q=7$

$\frac{pq}{10} =7$

pq=7*10

pq=70

$q=\frac{70}{p}$

Hope this helps, have a BLESSED and wonderful day! :-)

Answer:

-1

Step-by-step explanation:

Square both sides of the equation. (That is what is meant by "use the inverse relationship.")

$i^2=(\sqrt{-1})^2\\i^2=\boxed{-1} \qquad\text{simplify}$

A community theater uses the function p (d) = (-4d+40) (d−40) to model the profit (in dollars) expected in a weekend when the ti

The theater make the maximum profit at d = $25. Then the maximum profit of the theatre is $ 900.

<h3>What is differentiation?</h3>

The rate of change of a function with respect to the variable is called differentiation. It may be increasing or decreasing.

A community theater uses the function P(d) = (− 4d + 40) (d − 40) to model the profit (in dollars) expected on a weekend when the tickets to a comedy show are priced at d dollars each.

Then the maximum profit of the theatre will be

The function is P(d) = (− 4d + 40) (d − 40)

Differentiate the function with respect to d and put it equal to zero for maximum or minimum profit.

$\begin{aligned} \dfrac{\mathrm{d} }{\mathrm{d} d}P(d) &= 0\\\\\dfrac{\mathrm{d} }{\mathrm{d} d}(- 4d + 40) (d - 40) &= 0\\\\(-4d+40) -4 (d-40) &= 0\\\\-8d + 200 &= 0\\\\d &= 25 \end{aligned}$

Then the checking for maximum or minimum, again differentiate, we have

$\begin{aligned} \dfrac{\mathrm{d} }{\mathrm{d} d}P(d) &= \dfrac{\mathrm{d} }{\mathrm{d} d}(- 4d + 40) (d - 40) \\\\\dfrac{\mathrm{d} }{\mathrm{d} d}P(d) &= \dfrac{\mathrm{d} }{\mathrm{d} d}(-8d + 200) \\\\\dfrac{\mathrm{d} }{\mathrm{d} d}P(d) &= -8\\\\ \dfrac{\mathrm{d} }{\mathrm{d} d}P(d) & < 0\end{aligned}$

The value is less than zero hence maximum value will occur at d = 25.

Then maximum profit will be

P(d) = (− 4×25 + 40) (25 − 40)

P(d) = (− 100 + 40) (−15)

P(d) = (− 60) (− 15)

P(d) = $ 900
