Explanation:

Step1: Define total cost equation

Let $B$ = number of buckets. Total cost: $20 + 2B = 40$

Step2: Isolate variable term

Subtract 20 from both sides: $2B = 40 - 20$
$2B = 20$

Step3: Solve for B

Divide by 2: $B = \frac{20}{2}$
$B = 10$

Step4: Select complete sentence

Match result to proper sentence format.

Answer:

You can buy 10 buckets of golf balls.
