Tara is saving up to buy a new clarinet. She already has $10 saved. The clarinet costs $90. She plans to sell her old books to make the money. She sells each book of hers for $5. However, when she is halfway towards her goal, she loses all her savings and has to start over. How many books does she sell in total by the time she reaches her goal?
How much money does Tara have halfway towards her goal? ** Halfway towards her goal is $45 because 90 / 2 = <<90/2=45>>45
How many books does Tara sell before she loses the money? ** She sells $35 worth of books before she loses the money because 45 - 10 = <<45-10=35>>35
How many books does Tara sell before losing the money? ** She sells 7 books before losing her money because 35 / 7 = <<35/7=5>>5
How many books does Tara sell after losing the money? ** She then sells 18 books because 90 / 5 = <<90/5=18>>18
How many books does Tara sell in total by the time she reaches her goal? ** She sells 25 books in total because 18 + 7 = <<18+7=25>>25
