A middle school band is selling candy bars and nuts to raise money for a field trip. Each candy bar, b, costs $1.50 and each box of nuts, n, costs $4.00. If they raised $418, what expression shows the portion that came from candy bar sales?

1.5b = 418 - 4n (all in dollars)

Step-by-step explanation:

Let b represent the number of candy bars sold and n the number of box of nuts sold.

Given that each;

Candy bar costs $1.50

box of nut $4.00

Amount raised from candy bars = $1.50 * b

Amount raised from box of nut = $4.00 * n

Total amount raised = $418

The equation for the total amount raised is;

1.50 * b + 4.00 * n = 418

1.5b + 4n = 418

The portion that came from candy bars is;

Making 1.5b the subject of formula;

1.5b = 418 - 4n
