Question

Mr. Winter bought four packages of ground beef. The second package weighed three times as much as the first, and the third package weighed half as much as the second. The fourth package weighed fifteen ounces, which was three ounces more than the third package. How many ounces of meat did Mr. Winter buy?
Solve algebraically.

Answer 1

1st package --- x
2nd package -- 3x
3rd package -- 3x/2

4th: 3x/2 + 3 = 15
3x + 6 = 30
3x = 24
x=8

1st : 8
2nd : 24
3rd : 12
4th :15
Add them up.
