A 3-gallon container of laundry detergent costs $20.76. What is the price per quart?
nlexa [21]

Answer:

The answer to your question is: 1 quart = $1.73

Step-by-step explanation:

data

3-gallon cost = $20.76

cost of 1 quart = ?

Rule of three

                    1 gallon ---------------  4 quarts

                    3 gallons ---------------    x

                 x = 12 quarts

                12 quarts --------------- $20.76

                  1 quart ----------------    x

x = 1x 20.76 / 12 = $ 1.73

A costume designer has 40 yards of red fabric to make costumes for a musical in which 8 performers will wear red dresses and 14
Fed [463]

Answer:

38.5 yards used

Step-by-step explanation:

Yes he has enough fabric

to get the answer you must take the total number of dresses (8) and multiply it by 3 1/2 (3.5) because thats how much it takes to create one dress.

3.5 x 8 = 28

Now take the number of scarfs (14) and multiply it by 3/4 (0.75) because thats now much it takes to create a single scarf

0.75 x 14 = 10.5

now you add both of the answers

10.5 + 28 = 38.5

since 38.5 < 40 it means that he has enough fabric to create all the costumes for the musical
