Answer: 260 gallons
Step-by-step explanation:
We can use a proportion to solve this problem. We know that a family used 15 gallons of milk every 3 weeks. Since the problem asks for how much they will need for a year, we can gather that a year is 52 weeks. We can come up with the following proportion.
[cross multiply]
[divide both sides by 3]
Therefore, they will need to purchare 260 gallons.
75% of the original price is $33.
33 = 75% * x
33 = 75/100 * x
33 = 3/4 * x
x = 33 * 4/3
x = 11 * 4
x = 44
The original price of the sweater was $44.
We are given the equation:
0.6 x + 4.8 = 7.2
In this case, the multiplication property of equality states
that whatever is multiplied on one side should also be multiplied on the other
side. Now we need to find the number that will make everything a whole number,
in this case 5. Multiply everything by 5:
5 * (0.6 x + 4.8 = 7.2)
3 x + 24 = 36
However we can see that we can still further simplify the
equation by multiplying everything by 1/3:
(1/3) * (3 x + 24 = 36)
x + 8 = 12
or
x = 4
