This could be solved as an Arithmetic Sequence, but we'll do it the easy way . . .A boy sold 100 tickets in five days.
Each day he sold 6 more tickets than he had sold the previous day.
How many tickets did he sell on the first day?
Let = number tickets he sold the first day.
He sold a total of: . tickets.
