Question: Faith's neighborhood, with a total of 20 homes, decided to install solar panels. Each home needed 10 panels capable of providing their power needs. The supplier of the panels brought 50 panels less than the required amount. The neighbors agreed to only install the panels up to where they'd be finished. How many homes had their panels installed?
Answer: The total number of panels required is 20 * 10 = 200 panels. When 50 failed to be delivered, the total number available for use became 200 - 50 = 150 panels. If each home requires 10 panels, the number of homes that had panels installed is 150 / 10 = 15 homes. The answer is 15.

Q: In a truck, there are 26 pink hard hats, 15 green hard hats, and 24 yellow hard hats. If Carl takes away 4 pink hard hats, and John takes away 6 pink hard hats and twice as many green hard hats as the number of pink hard hats that he removed, then calculate the total number of hard hats that remained in the truck.
A: If there were 26 pink hard hats and Carl took away 4 pink hard hats, the number of pink hard hats that remained is 26 - 4 = 22. John also took away 6 pink hard hats, leaving 22 - 6 = 16 pink hard hats in the truck. If John also took twice as many green hard hats as pink hard hats, he took 2 * 6 = 12 green hard hats. The total number of green hard hats that remained in the truck is 15 - 12 = 3. In the truck, after some are taken, there were 3 green hard hats + 16 pink hard hats = 19 hard hats in the truck. Altogether, 19 green and pink hard hats + 24 yellow hards hats = 43 hard hats remained in the truck. The answer is 43.
