Let's break down the problem step by step:
1. Start with the equation: Revenue - Costs = Profit
2. We know the cost of ingredients is $28, so the cost equation is: $28
3. The revenue equation is: Revenue = $4 * c (where c represents the number of containers sold)
4. We want to find the number of containers needed to earn $20 in profit, so the profit equation is: Profit = $20
5. Substituting the equations, we get: $4c - $28 = $20
6. Now, let's solve for c by isolating it: $4c = $20 + $28
7. Simplifying the right side of the equation, we get: $4c = $48
8. Dividing both sides of the equation by $4, we get: c = 12
Therefore, you need to sell 12 containers of cookies to earn $20 in profit.
You spend $28 on ingredients to make cookies. You charge $4 per container of cookies. How many containers do you need to sell to earn $20 in profit?
CLEAR CHECK
Write an equation to represent the problem. Let c represent the number of containers of cookies you need to sell.
= c −
How many containers of cookies do you need to sell?
You need to sell containers of cookies.
