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?

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

"Jonathon has a bag full of 14 balls to sell."

We know that x=baseball and y=volleyball. And He has 14 balls in total. What would the equation be?

Answer 2

c

Answer 3

"He sells the baseballs for $2 dollars and the volleyballs for $5 and earns a total of $43"

Again x=baseball and y=volleyball

He sells x (baseball) for $2, so that looks like 2x.
He sells y (volleyball) for $5, so that looks like 5y.

You add them together and the total would be 43.

What would the equation look like?

Answer 4

I asked about the equation and not a letter. :)

Answer 5

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

Answer 6

Yes. :)

Answer 10

Brad can make 4 key chains in an hour. Velma can make only 3 key chains in an hour, but she already has 6 completed key chains. Explain to Brad how he can use a system of equations to determine when he will have the same number of key chains as Velma. Use complete sentences.
