B)
so, the farm can support 20 horses at most
Step-by-step explanation
Step 1
make the inequality
Let x represent the number of horses, so
if a horse needs 1. 75 acres , the number of acres needed by x horse will be x times that value
so
also, we are told that Sunshi acre farm has at most 35 acres available, so. in other words the total acres must be equal or smaller than 35
so
now, combine the expressions
Step 2
find the possible number of horses farm can support
so, let's solve for x
so, the farm can support 20 horses at most
I hope this helps you
