if x is the total you have 14 wrong you can write:
$\frac{100}{28} = \frac{x}{14}$
x=(100/28)*14=50 questions

In December she would have saved $1585 because 1235 + 250 = 1485. You can find how much money she raised in those 2 months by adding the totals of both months together, so 1485 + 1235 = 2720. She saved $2720 in the 2 months.
