so abtrehearn is right. since \[14\times 7+3=101\] which tells us that there are 13 +1 because of the first one

I was thinking what LAMrc said but my book says the answer is 14. If 7 doesn't go into 3 wouldn't the remainder be 7 : ?

Here's how I worked it out: 10 is the first positive integer that can be divide by 7 with a remainder of 3. The next is 17, then 24, ... all the way to 94.

10, 17, 24, ..., 94 That should be 13 terms.

The number 3 is also in the list of positive integers less than 100 whose remainder is 3 upon dividing by 7. The list is {3, 10, 17, ... , 94}.

I guess I missed the first one, i.e., 3.
