Stephanie goes shopping on Sunday. She
just olya [345]
Started with: $60
left with: $10
items bought: 20

60 - 10 = 50 < amount spent
  
50/20 = amount spent/items bought
           = $ 2.50 < each chocolate

you can check this by multiplying the items bought and the amount each item cost to get how much you spent

20 × 2.5 = 50

Stephanie started off with 60 dollars and ended with 10 dollars

60 - 50 = 10

hope this helps :)
