1)A painter charges $30 per room and a flat rate of $100. How much will it cost to have 6 rooms painted?

Lets turn this into an equation:

30 is the cost per room, where x is the number of rooms. 100 is the constant fee, it will not change. Y is the total cost. This gives us:

y = 30x + 100

6 rooms means that x = 6 and we need to find y.

y = 30(6) + 100

y = 180 + 100

y = 280

This means that it will cost $280 to paint 6 rooms.

I hope this helps! :)
