The Garcia family wants to paint their house. They have found a painter who will paint their house for $25 per hour, plus the cost of the paint. They need 10 cans of paint which cost $15 per can. Write an equation which can be used to find c, the cost of painting the house in terms of h, the amount of hours the painter paints?

• c = 25h +10

• c = 25h +15

• c = 25h +150

• c = 150h + 25
