After you get the equations: 3x + 4y =40 and 5x + 2y =34, use matrices and plug it into the graphing calculator which will give you the answers for x and y.
<span>X is going equal to 4 </span>
<span>and y is going to equal 7 </span>
<span>check: </span>
<span>3(4) + 4(7)= 40 </span>
<span>5(4) + 2(7)= 34
btw... never knew this is college level mathematics ^_^</span>
Answer:
Step-by-step explanation:
Solving for the Solution Set:
1. Let c and b represent candy and combo purchases, respectively.
.. amount = 3c +5b
2. amount ≤ 12
.. 3c +5b ≤ 12
3. amount ≥ 12
.. 3c +5b ≥ 12
4. amount = 12
.. 3c +5b = 12
.. (c, b) = (4, 0) . . . . . the only integer solution
