Sam opened a Pizza shop. The rent for the Pizza shop is $670 per month. Sam makes $5 for each Pizza that he sells. The following equation represents the profit he can make:
P = 5z – 670
How many Pizza’s must Sam sell in order to make $800 profit. P represents the profit while z represents the number of Pizzas that he must sell.
Answer: 290 Pizzas
Explanation:
P = 5z – 670 Original equation
800 = 5z – 670 Substitute 800 for the profit
800 + 650 = 5z Add 570 to both sides to isolate variable
1450 = 5z Isolate variable
z = 1450 / 5 = 290 Divide both sides by 5 to find z
