17. Aviva has collected 56 cans of food for disaster relief. Her goal is to collect 200 cans. Write and solve an equation to show how many more cans \( c \) she needs to reach her goal.

To find out how many more cans Aviva needs, we can set up the equation: \[ 56 + c = 200 \] Now, to solve for \( c \), we subtract 56 from both sides: \[ c = 200 - 56 \] \[ c = 144 \] So, Aviva needs 144 more cans to reach her goal of 200 cans. Now, does that inspire you to join a food drive? Every little bit helps, and who knows—you might just become a champion can-collector!
