Question

Jonathon has a bag full of 14 balls to sell. He sells the baseballs for $2 dollars and the volleyballs for $5 and earns a total of $43. If the baseballs are represented by x and the volleyballs are represented by y, which of the following systems of equations can be used to calculate the number of baseballs and volleyballs sold? (5 points)

x + y = 14, 2x + 5y = 43

x + y = 43, 2x + 5y = 14

x − x + y = 14, 2x + 5y = 43

x + y = 43, 5x + 2y = 14

Answer 1

its a because if you add the baseballs and the volleyballs you get 14 balls
so x + y = 14. only a has that

Answer 2

X+Y=14
2x+5y=43
Those are the equations
