A jazz band sells 31 large boxes of fruit and 74 small boxes of fruit for a fundraiser.
Greeley [361]

Part A)

The jazz band sells 31 large boxes of fruit and 74 small boxes of fruit.

For each large fruit box, the price is $20 and cost is $x.

Profit is defined as Price - Cost.

So, profit for one large fruit box = 20 - x

Profit for 31 large fruit boxes = 31(20 - x)

Price of each small fruit box is $10 and cost of each small fruit box is $y. The profit for each small fruit box is 10 - y.

Profit for 74 small fruit boxes = 74(10 - y)

The total profit for 31 large boxes and 74 small boxes will be:

Total profit = 31 (20 - x ) + 74(10 - y)

Using distributive property, we can simplify the above equation as:

Total profit = 31(20) - 31x +74(10) - 74y

Total profit = 1360 - 31x - 74y

Part B)

Cost of each large box is given to be $9. This means x = 9

Cost of each small box is given to be $4. This means y = 4

Using the values of x and y in the profit equation we can find the profit of the Jazz Band.

So, Jazz Band's Profit = 1360 - 31(9) - 74(4)

Jazz Band's Profit = $ 785

Thus the profit of Jazz Band will be $785.

Eloise's aunt cut 9.5 meters of ribbon into 4 equal sections and gave one of those sections to Eloise. Her friend Amelie has 2.5
Alinara [238K]

Answer:

0.125 meters

Step-by-step explanation:

Eloise's aunt cut 9.5 meters of ribbon into 4 equal sections and gave one of those sections to Eloise.

The length of the ribbon given to Eloise

= 9.5 meters/4

= 2.375 meters

Her friend Amelie has 2.5 meters of ribbon.

How much more ribbon does Amelie have than Eloise?

This is calculated as:

Number of meters of ribbon Amelie has - Number of meters if ribbon Eloise has

= 2.5 meter - 2.375 meters

= 0.125 meters

Therefore: Amelie has 0.125 meters of ribbon more than Eloise

The ratio of dimes to quarters in a money bag is 2:14. if the total numbers of coins is 48, how many quarters are there?
Bess [88]

Answer:

There are 42 quarters (and 6 dimes).

Step-by-step explanation:

The given ratio is 2:14.  But this does not tell us how many dimes nor how many quarters we have.  Instead, it's a ratio.  Modify this by multiplying numerator and denominator by n and then find n:

Number of dimes        2n

----------------------------- = -----

Number of quarters     14n

Then the total number of coins is 2n + 14n =48, implying that:

16n = 48, or n = 3.

Then the number of dimes is 2(n) = 2(3) = 6, and that of quarters is 14(n) =

14(3) = 42.

There are 42 quarters (and 6 dimes).  Notice how the total of 42 and 6 is 48.
