Sales in the printing business have doubled for james in each of the last three months. during the last month, he made a profit of $ 520. if the pattern continues, what will be his three month total profit at the end of the next three months?

Take 520 times two which equals 1,040 then take that times two which equals 2,080 then once again take that times two which equals 4,160. Last but not least take those last three numbers and add them together. This equals 7,280 which is your final answer ;) Hope this helped ;)
