Ms. Muir decided to make trail mix for her next excursion to collect rocks. Dried fruit cost
$6.00 per pound and the nuts cost $5.50 per pound. She spent $53.75 on 9.5 pounds of
trail mix. How many how many pounds of nuts, and how many pounds of fruit did she buy?

DF+N-53.75
6F +5.50N = 9,5
F+N= 9.5
6F + 5.50N = 53.75
