Answer:
Let's assume that the cost of a box of candy is "x" dollars.
According to the problem, Karen bought 3 boxes of candy and 2 small bags of popcorn, and paid $18.35. So we can write the equation:
3x + 2y = 18.35
Similarly, Holly bought 4 boxes of candy and 3 small bags of popcorn, and paid $26.05. So we can write the equation:
4x + 3y = 26.05
We want to find the cost of a box of candy, so we can solve for "x" using these two equations. One way to do this is to use elimination. If we multiply the first equation by 3 and the second equation by -2, we can eliminate the "y" term:
9x + 6y = 55.05
-8x - 6y = -52.10
Adding these two equations gives:
x = 2.95
So the cost of a box of candy is $2.95.
