You spend $28$28 on ingredients to make cookies. You charge $4$4 per container of cookies. How many containers do you need to sell to earn $20 in profit?
Let, the number of Containers = x
Then, Equation would be: 4x - 28 = 20
4x = 20 + 28
x = 48/4
x = 12
In short, Your Answer would be: 20 Containers
Hope this helps!
4x7=28 you need 7 just to break even then
4x5=20 you need 5 to make $20
7+5=12 You need 12 to make $20
