Assuming there are four weeks in a month, the author would earn an additional $600 ($75 x 2 x 4) per month by writing two extra columns. Therefore, the maximum monthly payment for the computer would be $150 ($600 - $450, the cost of two additional columns on a typewriter). So, the author should buy the computer only if the monthly payment is less than $150. Choice E is the only option that meets this criteria.
