A businessman was comparing his company's profits for two consecutive months. In November, n, were 0.04 thousand dollars more th
an in December, d. The two months had a combined income of 3.15 thousand dollars. Which system of equations could be used to determine the amount of profit for each month, in thousands of dollars? A)n+d = 3.15
n+0.04=d
N and d are both numbers of thousands of dollars. Thus, if n = 1, that means $1000.
Here n = d + 0.4. Note that in C, n+0.04=n is completely wrong. Similarly, in D, d = 0.04 = n is completely wrong. The "combined profit amount" for Nov. and Dec. is n + d = 3.15.
