The cost in dollars to produce x cups of lemonade is represented by the function C(x) = 10 + 0.20x. The revenue in dollars earned by selling x cups of lemonade is represented by the function R(x) = 0.50x. What is the minimum number of whole cups of lemonade that must be sold for the revenue to exceed the cost?

Answers

For the income to exceed the cost, a minimum of 34 complete cups of lemonade must be sold.

What is inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal.

Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), larger than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

The cost in dollars C(x) = 10 + 0.20x.

The revenue in dollars, R(x) = 0.50x.

For revenue to outpace cost

R(x) > C(x)

0.50x > 10 + 0.20x

0.50x - 0.20x > 10

0.30x > 10

x > 10/0.30

x > 33.333

Hence, For the income to exceed the cost, a minimum of 34 complete cups of lemonade must be sold.

#SPJ2

For revenue to exceed cost: R(x) > C(x)
0.50x > 10 + 0.20x
0.50x - 0.20x > 10
0.30x > 10
x > 10/0.30
x > 33.333

Therefore the minimum number of whole cups of lemonade that must be sold for the revenue to exceed the cost is 34.

Find the midpoint of the line segment whose endpoints are (-2, 5) and (4, -9).

Answers

Solving for the midpoint can be done by looking for the average of each of the given x-coordinates and y-coordinates. The 2 obtained averages are the new x-coordinate and y-coordinate. This shown below:

Midpoint = ( (-2 + 4)/2 , (5 + -9)/2 )
Midpoint = (1,-2)

Therefore, the new midpoint is (1,-2)

A chemist is mixing one solution that is 32% sodium and another solution that is 12% sodium how many liters of each type should the chemist use to produce 50 l of the solution that is 20% sodium

Answers

In order to solve the amount of each solution, we need to set up equations. We do as follows:

Let x = solution with 32% sodium
y = solution with 12% sodium

Overall balance
x + y = 50

Component balance
.32x + .12y = 50(.20) =10

Solving simultaneously,

x = 20
y = 30

Hope this answers the question. Have a nice day.
