Answer 2

Ron has 40 cattle.

B is correct.

Explanation:

Ron has 30 acres of grazing land for his cattle.

Each cattle requires
`(3)/(4)` of an acre.

Let us consider n number of cattle.

Total land graze by cattle =
`(3n)/(4)`

This should be less than equal to 30

We get an equation

`(3n)/(4)\leq 30`

Solve for n

`3x\leq 4* 30`

`x \leq 40`

Hence, Ron has 40 cattle.
