Answer:

80%

Step-by-step explanation:

home work = 10%

project grade = 50%

final exam = 40%

so

<u>homework  = 72</u>

100=10

72=?      cross multiply and get 7.2%

<u>project grade = 80</u>

100 = 50

80 = ?   cross multiply and get 40%

<u>final exam = 82</u>

100 = 40

82 = ?     cross multiply and get 32.8%

then add them altogether getting a total of 80%.

Sladkaya [172]
The correct statement is:
A gallon of Moo Milk costs $5.12 What is the price, in dollars, of an 8 ounce glass of Moo Milk? There are 128 ounces in 1 gallon.

Solution:
Cost of 1 gallon of Moo Milk = $ 5.12

1 gallon = 128 ounces, so we can write:

Cost of 128 ounces of Moo Milk = $ 5.12

Cost of 1 ounce of Moo Milk = $ 5.12/128 = $ 0.04

Cost of 8 ounces of Moo Milk = $ 0.04 x 8 = $ 0.32

Thus, 8 ounces of Moo Milk will cost $ 0.32
