Mina put $1,500 into her savings account in February. In March, she put twice as much money into her savings account as she put in February. Which expression could be used to find out how much she has saved altogether?
We know she saved twice as much in March as in February, so double the amount saved in February, 2(1500). Then add that to what was saved in February, which was $1500, to get 2(1500) + 1500, aka option D.
