3. A mother has $5.80 to buy some fruit for her extended family. She needs at least 9 pieces of fruit, in this case apples and pears are preffered. When going to the market she notes apples are worth$0.60 each while pears are \$0.70 each.

Let X be the number of apples and Y be the number of pears. How many of each can she buy for this amount of money given the costs of each?

Solve the system

$\displaystyle 0.6X+0.7Y=5.8$

$\displaystyle X+Y=9$
