They need to raise $1,680 for travel expenses. Each chocolate bar is being sold for $2, and each box contains 30 chocolate bars.
leonid [27]

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

Perform the operation: 3 gal, 1 qt. -1 gal, 3 qt.
Bumek [7]

Ah, college mathematics.

We must remember there are four quarts per gallon.  Let's convert everything to gallons:

3 \frac 1 4 - 1 \frac 3 4 = \frac{13}{4} - \frac{7}{4} = \frac{6}{4} = 1 \frac 2 4

We don't reduce because it's easy to see that's 1 gallon, 2 quarts, third choice.
