Final answer:
To determine the minimum number of vases she will have to sell to make a profit of at least $500, set up the inequality and solve for v. The minimum number of vases she will have to sell is 28.
Step-by-step explanation:
To determine the minimum number of vases she will have to sell to make a profit of at least $500, we need to set up an equation. The equation is:
P = 46.15v - 24v - 120
Where P is the profit and v is the number of vases sold. We want to find the value of v that makes P at least $500. So, we can set up the inequality:
46.15v - 24v - 120 ≥ 500
Combining like terms:
22.15v - 120 ≥ 500
Adding 120 to both sides:
22.15v ≥ 620
Dividing both sides by 22.15:
v ≥ 27.96
Since v represents the number of vases sold, it must be a whole number. Therefore, the minimum number of vases she will have to sell to make a profit of at least $500 is 28 vases.
