You are making cakes for a bake sale. Each box of cake costs $1 to buy. You also need to buy a pan to bake the cakes in, and the pan costs $20. If you want to make a profit of at least $50, how many cakes do you need to sell at the bake sale? Write and solve an inequality

70

Step-by-step explanation:

We have that profit equals profit minus cost.

In this case the profit must be at least $ 50 and they have a profit of $ 1 for each box of cakes in addition to a fixed cost of $ 20. Let x be the number of the box of cakes, then:

x - 20 => 50

that would be the inequality

Now to solve it:

x - 20 + 20 => 50 + 20

x => 70

This means that at least 70 boxes of cakes must be sold so that the profits are 50.

the answer to this question is 3/19
