Jefferson stops by a fast-food restaurant for a 3.50 cheeseburger every day. If he only ate at home and eliminated this cost, how much could she save after 10 weeks
If Jefferson stops eating a $3.50 cheeseburger every day and eats at home instead, he would save $3.50 for each day.
In a week, he would save 7 days x $3.50/day = $<<7*3.5=24.50>>24.50.
In 10 weeks, he would save 10 weeks x $24.50/week = $<<10*24.5=245.00>>245.00. Answer: \boxed{245}.

If Jefferson saves $3.50 per day by eating at home instead of buying a cheeseburger, he would save $3.50 x 7 days = $<<3.5*7=24.50>>24.50 per week.
Therefore, in 10 weeks, he could save $24.50 x 10 = $<<24.5*10=245>>245. Answer: \boxed{245}.
