Question

Jamal is buying ingredients to make a large batch of granola to sell at a school fair. He buys 3.9 pounds of walnuts for $5.18 per pound and 2.6 pounds of cashews for $6.12 per pound. How much change will he receive if he pays with two $20 bills?

Answer 1

$3.89

Explanation:

Let's find out how much the ingredients will cost altogether.

First, we multiply 3.9 pounds of walnuts by $5.18, since that is the cost of each pound. This will be the total cost of the walnuts.

`3.9 * 5.18\\` = $20.202

Second, we multiply 2.6 pounds of cashews by $6.12, since that is the cost of each pound for cashews. This will be the total cost of the cashews.

`2.6*6.12` = $15.912

Now, add the costs of the walnuts and cashews together to get:

$20.202 + $15.912 = $36.114

Jamal has two $20 dollar bills, meaning that he has 20 + 20 = $40 dollars in total.

Subtract the cost of the ingredients from the amount of money Jamal has:

40 - 36.114 = $3.886

Make sure to round to the nearest hundredth! Jamal will receive $3.89 in change.
