p832.8 the price of ground coffee beans is d dollars for 8 ounces and each ounce makes c cups of brewed coffee.In terms of c and d,what is the dollar cost of the ground coffee beans required to make 1cup of brewed coffee?(用字母表示)
我觉得是8c/d啊,貌似不对,
Answer:
1.) Coffee Problem:
For d dollars, you make 8c cups of coffee. So each cup of coffee costs d/(8c) dollars.
2.) Carpeting Problem:
"Square yard" means “平方码”. So 12 feet by 18 feet means (12/3) yards by (18/3) yards, or 4 yards by 6 yards, which is 4x6 = 24 square yards.
