f her store is r = 15n. the cost function of her store is c = 9n + 450. using your calculator, what is the break-even point of amanda's store?
1 answer:
Answer:
The break- even point is attained when n=75
Step-by-step explanation:
The break-even point is defined as the point where revenue is equal to cost.
We take the equation for revenue r=15n, and set it equal to the equation c=9n+450
15n=9n+450
Subtract 9n from both sides:
6n=450
Divide both sides by 6.
6n/6=450/6
n=75
The break- even point is attained when n=75....

Hello!
You find the area of a rectangle by the equation A = lw
A is area
l is length
w is width
Put in the values you know
180 = 3x * 6
Now you solve it algebraically
Divide both sides by 6
30 = 3x
Divide both sides by 3
10 = x
The answer is 10in
