Answer:

520

Step-by-step explanation:

Given that:

Profit function p(x) is :

P(x) = 8.50x- 1500

If the profit made = $2920 ; the number of pizza kits sold is :

Then p(x) = 2920

Putting p(x) = 2920 in the equation :

2920 = 8.50x - 1500

2920 + 1500 = 8.50x

4420 = 8.50x

Divide both sides by 8.50

4420 / 8.50 = 8.50x / 8.50

520 = x

Hence, number of pizza kits sold is 520
