Eric paints 8 rooms in 3 days for $600.
a. what is his painting rate in dollars per day?
b. how much does he receive on average for a room?
c. about how many rooms could eric paint in 6 days?

He earns 200 dollars per day. He earns 75 dollars per room. He can paint about 16 rooms in 6 days.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
