Janet wins the lottery and receives $100 the first year. In the following years, she receives $50
more each year. (That is, Janet receives $150 the second year, $200 the third year, and so
on.) How much will Janet receive, in total, after 10 years?
100 + 150 + 200 + 250 + 300 + 350 + 400 + 450 + 500 + 550 = ?
Add them up.

3250
