a soccer team is selling pizzas for $6 each each piece that cost $4 to make the team has 10 players and must have raised $1,200 for equipment and uniform how many pizzas does the team need to sell

Well let's say we have $0 and this is purchased for the sake of this answer.

We would have $-4 and one slice would give us a profit of $2. This is rinse and repeat and then you would have to sell 600 pizzas.

Because then:

$6 X 600 = $3600

$4 X 600 = $2400

$3600 - $2400 = $1200

So you would have to sell 600 pizzas to raise enough money
