Explain simply why 9 is the correct answer to: Chad is hosting a BBQ on the hottest day of the year, where there will be a total of 15 people. He will need 2 pounds of ice per person to account for the heat. One pound bags of ice are sold for $3.00 for a pack of 10. How much will he spend on ice?. Explanation:
He's inviting 15 guests and will need 2 pounds per person so he will need 15 * 2 = 30 pounds of ice. Ice is sold in 10 - pound bags and he needs 30 pounds so he will need 30 / 10 = 3 bags of ice. Each bag is $3.00 and he needs 3 bags so they will cost 3 * 3 = $9.00.
