Question: Emily has 6 marbles. Megan gives Emily double the number she has. Emily then gives Megan back half of her new total plus 1. How many marbles does Emily have now? Is final answer 8?
Answer: Megan gives Emily 6*2=<<6*2=12>>12 marbles.
Emily then has 6+12=<<6+12=18>>18 marbles.
Emily gives Megan 18/2+1=<<18/2+1=10>>10 marbles.
Emily has 18-10=<<18-10=8>>8 marbles now.
