CaHeK987 [17]

Answer:

The number of skateboard company sell during the month of August = 55

Step-by-step explanation:

We have given,

Profit function for Bob, P = x²+ 10x - 12

Bob's profit during August month is $3,563

That means, P = $3,563

We can use the profit formula given for Bob's profit:

P = x² + 10x - 12

Plug P =$3,563 in above formula.

i.e 3,563 = x² + 10x - 12

or 0 = x² + 10x -12 - 3,563

or 0 = x² + 10x - 3575

or x = 55, -65

Since number of skate boards can not be negative.

So we consider x= 55

Hence the number of skateboard company sell during the month of August = 55.

A washer and dryer cost $793 combined, the washer costs $93 more than the dryer. What is the cost of the dryer?

frosja888 [35]

The dryer costs x.
The washer costs $93 more than the dryer, so it costs x+93.
The washer and the dryer cost $793 altogether.

$x+x+93=793 \\
2x=793-93 \\
2x=700 \\
x=\frac{700}{2} \\
x=350$

The cost of the dryer is $350.
