Alex is saving up for a new car. He already has $14,500 saved up and the car costs $14,600. He decides that to make the last of the money he will deliver groceries for people in the neighborhood.  He charges $1.5 per trip and then 5% of the price of the groceries. If he makes 40 trips and has saved up enough, how many dollars' worth of groceries did he deliver?
How much money does Alex need to make? ** He needs to save up $100 because 14,600 - 14,500 = <<14600-14500=100>>100
How much money did Alex earn? ** He earned $60 off trips because 40 x 1.5 = <<40*1.5=60>>60
How much money did Alex earn from groceries? ** He earned $40 off groceries because 100 - 60 = <<100-60=40>>40
How much money did Alex deliver? ** He delivered $800 in groceries because 40 / .05 = <<40/.05=800>>800
