    .2 is the decimal representation of 20/100 which means we have 20% increase

    Jason is 48% short of a goal he made for the week. His goal is to earn $375. For each CD player he sells, he earns $45. How many CD players does he need to sell to meet his goal ?

    he needs to sell 8.3 which is a rediculous number... so 8 is not enough, so he has to sell 9 of them right?
