<bot>: How much will the scoops cost? ** Each scoop cost $1.50. If she buys 2, she gets one free. So it will cost her 2 * 1.50 = $<<2*1.50=3.00>>3.00 for thee scoops total.
How much does each scoop cost? ** If you break it down, 3 scoops of ice cream cost $3.00 so 3/3 = $<<3/3=1.00>>1.00 per scoop
How many scoops should Erin buy? ** Erin has $6.00 and each scoop ends up costing $1.00 each then 6/1 = <<6/1=6>>6 scoops total
