Question

The sporting equipment has been sorted into baseballs and bats. The number of baseballs is four less than three times the number of bats. The equipment is 80% baseballs. Choose the equation that best represents this scenario

Answer 1

x/(3x-4) = 20/80

Answer 2

Answer: Second Option

`(x)/(3x-4) = (20)/(80)`

Explanation:

The baseball team is composed of bats and balls.

Call x the number of bats and call z the number of balls.

Then we know that:

The number of baseballs is four less than three times the number of bats.

This is:

`z = 3x-4` (I)

Then we know that the team is 80% baseballs

This is:

`(x)/(z) = (0.2)/(0.8)` (II)

We substitute the first equation in the second and we have:

`(x)/(3x-4) = (0.2)/(0.8)\\\\(x)/(3x-4) = (20)/(80)`
