We need to find how many candy bars they need to sell to make at least $400
We know that they already raised $120.
We also know each candy cost $1.50 a piece.
We know that they need to make $400.
Represent this as an equation:
400 = 1.50x + 120
x = amount of candy bars
Solve the equation to get how many candy bars they need to sell:
400 = 1.50x + 120
Subtract 120 from both sides
280 = 1.50x
Divide both sides by 1.50
186.66 = x
Round to the nearest whole
187 = x
Answer:
They would need to sell at least 187 candy bars
