+2828+
1212
+100100=> seems to be all numbers are doubled

I guess your numbers are 28,12, and 100

+28+%2B+12d+ is the number of shells she has after +d+ days

the number of days it will take for her to have over +100+ shells is found by solving:
++28+%2B+12d+%3E+100+

Subtract +28+ from both sides:
++28-28+%2B+12d+%3E+100+-28
+12d+%3E+72+
+d+%3E+72%2F12+
+d+%3E+6+

This means she won't have more than 100 shells until the 7th day.

I will assume that the information is supposed to be that she has 28 now and collects 12 more each day, and the inequality is supposed to represent the number of days it will take her to have more than 100.

28+%2B+12d+%3E+100
