Mr. Brown bought a television set and paid $110 as the first installment. If he increases each payment by $20 and pays a total of 6 installments, how much will the television set have cost him?
It will cost him $230 because you take 20 and times it by 6 because that's how many installments he had and you get $120 then you add the $110 that he bought the television set for and that will give you $230
