Question

Alexander and his children went into a grocery store and he bought $6 worth of

bananas and peaches. Each banana costs $0.60 and each peach costs $1.50. He
bought a total of 7 bananas and peaches altogether. Graphically solve a system of
equations in order to determine the number of bananas, x, and the number of
peaches, y, that Alexander bought.

Answer 1

Alexander bought 2 peaches and 5 bananas.

Explanation:

Since Alexander and his children went into a grocery store and he bought $ 6 worth of bananas and peaches, and each banana costs $ 0.60 and each peach costs $ 1.50, and he bought a total of 7 bananas and peaches altogether, in order to determine the number of bananas, x, and the number of peaches, y, that Alexander bought, the following calculation must be performed:

1.5 x 7 + 0.6 x 0 = 10.5

1.5 x 6 + 0.6 x 1 = 9.6

1.5 x 5 + 0.6 x 2 = 8.7

1.5 x 4 + 0.6 x 3 = 7.8

1.5 x 3 + 0.6 x 4 = 6.9

1.5 x 2 + 0.6 x 5 = 6

Therefore, Alexander bought 2 peaches and 5 bananas.
