Answer:

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.
