    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
