Bindle founders wisely approached paid marketing and decided to allocate a specific budget for Facebook or Twitter campaigns. That way we can always control ourselves and make sure we don’t underspend or overspend.
In this exercise let’s practice our grouping and summing technique and answer the question: “How much money was spent in total for all Facebook campaigns?”
Type integer part of the number to the answer field. Example: if the total spend was 182.31111 submit 182 as an answer.
