Question

They need to raise $1,680 for travel expenses. Each chocolate bar is being sold for $2, and each box contains 30 chocolate bars. There are seven scholars on the team and they agree to each sell the same number of boxes. How many boxes will each scholar have to sell in order to raise enough money to cover the team's travel expenses?

Answer 1

Answer:

Each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses

Step-by-step explanation:

Let x denotes number of boxes to be sold by each scholar to raise enough money to cover the team's travel expenses.

Number of scholars = 7

Total number of boxes $=7x$

Total number of chocolate bars $=(7x)(30)=210x$

Price of 1 chocolate bar = $2

Price of $210x$ chocolate bars $=210x(2)=\ 420x$

Also,

Total amount to be raised for travel expenses = $1680

So,

$1680=420x\\x=\frac{1680}{420}\\ x=4$

Therefore,

each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses
