Option C. [(15.35 + (2.25 x 3) - 2) ÷ 3] is the expression that can be used to find the amount each person paid.
First, they bought a watercolor paint box for $15.35.
Then, they bought 3 brushes for $2.25 each, which comes out to $6.75.
With a coupon for $2.00 off their purchase, the new total cost is $15.35 + $6.75 - $2.00 = $20.10.
Since they split the remaining cost equally, each person paid $20.10 ÷ 3 = $6.70.
Therefore, option C is the correct expression to find the amount each person paid.
