Best ResponseYou've already chosen the best response.2so abtrehearn is right. since \[14\times 7+3=101\] which tells us that there are 13 +1 because of the first one

Best ResponseYou've already chosen the best response.0I 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 : ?

Best ResponseYou've already chosen the best response.0Here'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.

Best ResponseYou've already chosen the best response.010, 17, 24, ..., 94 That should be 13 terms.

Best ResponseYou've already chosen the best response.1The 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}.

Best ResponseYou've already chosen the best response.0I guess I missed the first one, i.e., 3.
