Had I given this problem, I'd solve it in this way:
+
+ . . . +
= one click in Excel = 0.04969...
= 201.25 (approximately, with 2 valid decimal places)
which gives the ANSWER 201 to the problem's question.
Honestly, I do not see any reason and any Math idea (at the school Math level) behind this problem.
There is NOTHING TO LEARN from it . . . , which means that we (you and me) spent our time for nothing, solving it . . .
Another possible answer is THIS: take your calculator and make all calculations on your own.
It is not Algebra, actually: it is ARITHMETIC.
