Question 31 • Algebra II
Let the selling prices of a kitchen, bathroom, and shower faucet be k, b, and s. Comparing February with January gives 2k + 4b + s = 620; using the January and March totals as well gives k = 90, b = 80, and s = 120. The profit on one shower faucet is 15% of $120, which is $18, so the answer is $18.00.
