The Jones family is considering which one of two businesses will mow their lawn this summer. Lon's Lawns charges a flat rate of $32 for each mow but
offers the eighth mow free. Gilbert's Grass Care charges an annual fee of $50
plus $25 for each mow. If they know they will need their lawn mowed at least
10 times this summer, which set of equations can the Jones family use to help
determine which business would be the most cost efficient?
