4. At a discount furniture store, Chris offers the salesperson $600 for a couch and a chair. The store charges 8% sales tax. If
the salesperson accepts the offer, what is the cost of the furniture, including tax? Round your answer to the nearest hundredth. 5. Shelly earned 20% more money waitressing this week than last week. Last week, she earned $72. How much money did she earn this week? Round your to the nearest hundredth. 6. A 24 ounce box of Cinnamon Crunchers cereal costs $3.99. At this rate, what is the cost of a 36 ounce box of Cinnamon Crunchers? Round your to the nearest hundredth.
You take the percent (we'll take 4 for example, so 8%) and change it to a decimal: .08. You then multiply the decimal (.08) by your other number (in this case $600) and the resulting number is your answer, but not final. Take whatever the answer was (in this case 48) and add it to the orignal number (600) to get $648.
