If we ask the question a different way, that answer is much easier to see. The company makes $0.55 ($1.20 less the $0.65) on each product. so how many of these products will need to be made to cover the initial $9,900 equipment cost. 9,900/0.55 will give us the answer. 9,900/0.55 is 18,000 ==> the correct answer is D.

Let x = the number of units produced AND sold
TOTAL COST
If each unit of the product costs $0.65 to produce, then it costs 0.65x dollars to produce x units
We must also add the $9,900 investment in equipment
So, TOTAL COST = 0.65x + 9900
TOTAL REVENUE
If each unit sells for $1.20 to produce, then selling x units results in TOTAL SALES of 1.2x dollars
We want: TOTAL REVENUE = TOTAL COST
In other words: 1.2x = 0.65x + 9900
Subtract 0.65x from both sides: 0.55x = 9900
Solve: x = 9900/0.55
PRO TIP: We know that 9900/0.5 = 19,800
Since 0.55 is a bit bigger than 0.5, we know that 9900/0.55 = a little bit LESS THAN 19,800
Answer: D
