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 weeks?
Since the profit doubles at the end of each month
If the profit at the end of 2rd month is 520 $, the profit at the end of 4th month will be 520 + 520 = 1040
Profit at the end of 3 weeks after the 3rd month = 520 + (520*3/4) = 520 +390 =910$
