James made $4000 in January. The next month he made twice as much. In March, however, James made $2000 less than in February. How much has James made so far this year? Think carefully first, then make a decision:
In February James made 4000 * 2 = 8000. In March James made 8000 - 2000 = 6000. In total for the year James has made 4000 + 8000 + 6000 = $18000. So, the answer is 18000.
