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.

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.
check :
is 15 equal to 3 more than 12 ? YES
