    1. Wheel World sold 875 cars last year. If sales this year are 120% of sales last year, how many cars will Wheel World sell this year?<\/li>\n<\/ol>\n

      Solution<\/p>\n

        1. \u00a0 The \u201csuggested retail\u2019 price of a certain camera is $340, but a discount store sells the camera at a 30% discount. What is the price of the camera at the discount store?<\/li>\n<\/ol>\n

          Solution<\/p>\n

          If there is a 30% discount then 70% of the price is kept.<\/p>\n

          Multiply 340 by .70 = 238<\/p>\n

          So the camera at the discounted price is $238<\/p>\n

           <\/p>\n

          1. \u00a0 Mr. J. Doe has a taxable income of $9000. If the income tax rate is 16% on the first $4000 of income, 19% on the next $4000, and 23% on the next $1000, how much is Mr. Doe\u2019s tax?<\/li>\n<\/ol>\n

            Solution<\/p>\n

            Multiply 4000 by .16 = 640<\/p>\n

            Multiply 4000 by .19 = 760<\/p>\n

            Multiply 1000 by .23 = 230<\/p>\n

             <\/p>\n

            640 + 760 + 230 = 1630<\/p>\n

                      .40x = 5000<\/p>\n

                      x = 12500<\/p>\n

                            If Elmo made 54 of 80 then he missed 26..<\/p>\n

                            Divide 26 by 80 = .325\u00a0 = 32.5%<\/p>\n
