Question

Keith uses this formula to calculate the monthly profit of his bicycle store.

P = 400n - 7, 200
In the formula, P is the monthly profit and n is the number of bicycles sold in a month. How many bicycles must he sell to make a profit of exactly $2,000 in a month?
A. 13 bicycles
B. 17 bicycles
C. 23 bicycles

Answer 1

Keith must sell 23 bicycles to make a profit of exactly $2000 in a month. The answer is C.

Explanation:

To solve this problem, we need to find the value of n that makes the equation P = 2000 hold true.

Substituting 2000 for P in the given equation, we get:

2000 = 400n - 7200

Adding 7200 to both sides, we get:

9200 = 400n

Dividing both sides by 400, we get:

n = 23

Therefore, Keith must sell 23 bicycles to make a profit of exactly $2000 in a month. The answer is C.
