Problem #1
To produce x units of a religious medal costs C(x) = 12x +39 . The revenue is R(x) = 25x . Both C(x) and R(x) are in dollars.
a) find the break even quantity.
for this i got: that the break even quantity is : 3
b) Find the profit from 250 units?
for this i got: the profit of 250 unit s sold is $ -3014
c) Find the number of units that must be produced for a profit of $130?
For this i got : -19.6666666667 units.
Problem #2
On a summer day, the surface water of a lake is at a temperature of 30 C . What is this temperature in Fahrenheit?

You can put this solution on YOUR website!
Cost of producing the medals is:
The revenue (income) from selling the medals is: Both amounts in dollars.
1) The break-even quantity is found when the the revenue equals the cost, so setting R = C.
Subtract 12x from both sides.
Divide both sides by 13.
The break-even quantity, which is just what you had.
2) To find the profit P, you subtract the cost from the revenue.

Simplify this.

For 250 units, x = 250

Profit on 250 units is $3,211.00
Notice that your answer was a negative quantity and this would indicate a loss.
3) The number of units sold to make a profit of $130.00 is found by:
Substitute P = 130 and solve for x.
Add 39 to both sides.
Divide both sides by 13.
You would need to sell 13 units to make a profit of $130.00
4) Remember: Substitute C = 30.
