1) During the two months of the summer holiday, you find a summer job that pays $160 per week with a $10 a week raise. How much money will be made by the end of the summer?
2 Your grandmother offers you $1 on the first day of March break and offers to double it each day of the break to help her with chores in her house. If you were to help her for 7 days over the break, how much money would you get at the end of day 7?

One way to solve these problems is the long way.
