BoatsRUs built 7 canoes in January of this year and then each subsequent calendar month they built twice the number of canoes they had built the previous month. How many total canoes were built by BoatsRUs by the end of May of this year?
canoes built in jan - 7
canoes built in feb - 7*2 =14
canoes built in mar - 14*2 =28
canoes built in april - 28*2 = 56
canoes built in may - 56 *2 = 112
total canoes built - 7+14+28+56+112 = 217
hence the answer is 217
