<human>:  Julieta went to the store to buy a backpack and three ring-binders for her school supplies. She knew the backpack was $50, and each ring-binder cost was $20. However, at the store, she found out that the price of a back had increased by $5, and the price of a ring-binder had reduced by $2. Calculate the total amount of money Julieta spent at the store.
<bot>: How much did the backpack cost initially? ** Initially, a backpack cost was $50; when it increased by $5, the price became $50+$5 = $<<50+5=55>>55
How much did the ring-binder cost initially? ** The price of a ring-binder $20, when it reduced by $2, the price became $20-$2 = $<<20-2=18>>18
How much did Julieta spend on the ring-binders? ** If she wanted to buy 3 ring-binders, she spent $18*3 = $<<18*3=54>>54
How much money did Julieta spend at the store? ** In total, Julieta spent $55+$54 = $<<55+54=109>>109
