Let V pounds of Veal & P pounds of Pork be used in the Meatloaf
Given:
V+P=9 ---> Equation 1

Veals costs \$6/pound and Pork costs \$3/pound
Given:
6V+3P=36 ---> Equation 2

Solving both equations gives, V=3 and P=6

Therefore, how many more pounds are used of pork than of veal = 3 pounds

To prepare his famous meatloaf, Gordon uses veal, which costs \$6 per pound, and pork, which costs \$3 per pound. If the meatloaf weighs 9 pounds and costs \$36, how many more pounds are used of pork than of veal?

A. 3
B. 4
C. 6
D. 7
E. 9

OFFICIAL SOLUTION

To solve algebraically, we can set up two equations: v + p = 9 and 6v + 3p = 36. Multiply the first equation by 3 to get 3v + 3p = 27, and subtract it from the second equation, leaving us with 3v = 9, or v = 3. Plugging back in to the first equation gives us p = 6, and our final step is 6 - 3 = 3.

Alternatively, we know that the meatloaf price per pound is 36/9 = 4, and we can use the “tug of war” method to figure out the ratio of veal to pork: 3 ____ 4 _____ 6, so veal:pork is 1:2. With the total of 9 pounds, we know that it must be veal:pork = 3:6, giving us a difference of 3 pounds.
