Timothy wants to buy a skateboard. It costs $17.25. Every week he saves $1.20 more than the week before. After saving for a number of weeks, he bought the skateboard.
(a) What is the least number of weeks he needs to save enough to buy the skateboard?
(b) How much of his savings did he have left after buying the skateboard?
Do we assume that Timothy started saving $1.20 on the first week? The question did not state how much Timothy saved on the first week.
