Ashley and Duncan just created their January 2019 income and expense statement. They spent their combined $3,500 gross monthly income on the following expenses: $350 for tithing, $1,000 on rent, $400 to their Roth retirement plan, $1,000 on taxes, $300 on food and eating out, $100 on entertainment, and the rest in their savings account. They decide that for their February budget they want to invest an extra $100 in their Roth retirement (for a total of $500), cut each remaining variable category in half, and put the rest into savings. If all goes according to plan, how much money will Ashley and Duncan put towards savings in February?
