Last week , it cost Hong $39.50 to buy a 5 kilogram (kg) bag of coffee beans. Each kilogram cost the same. This week, Hong can buy a 8 kilogram bag of coffee beans at the same cost for each kilogram as last week.
Cost for each kilogram: $ ______
How much would it cost him to buy a 8 kilogram bag of coffee beans? $ _____
To find the cost for each kilogram, we need to divide the total cost by the number of kilograms. Thus, the cost for each kilogram is $39.50 / 5 kg = $<<39.50/5=7.90>>7.90.
Therefore, it would cost him $7.90 * 8 kg = $<<7.90*8=63.20>>63.20 to buy an 8 kilogram bag of coffee beans.
