A possible answer to this question is 10 cans of "wet food" and 15 bags of "dry food". 10 cans of wet food make $1.50 * 10 = $15 and 15 bags of dry food make $3.00 * 15 = $45. $45 + $15 = $60. We can find answers by creating this equation. $1.50c + $3.00b = $60 where c and b represent the number of "wet food" cans and "dry food" bags, respectively. We can easily substitute numbers and solve for the other quantity that will satisfy the condition of total cost adding up to $60.
