Question
Amanda is buying cookies for her friends. 6 of her friends ask for 5 cookies each and 8 of her friends ask for 3 cookies each.If there are 20 cookies in each packet, how many packets of cookies should Amanda buy
Solution
Step 1: Calculate the total number of cookies Amanda's friends asked for.
For the 6 friends who asked for 5 cookies each, the total number of cookies is 6 friends * 5 cookies/friend = 30 cookies.
For the 8 friends who asked for 3 cookies each, the total number of cookies is 8 friends * 3 cookies/friend = 24 cookies.
Step 2: Add the total number of cookies together.
The total number of cookies Amanda's friends asked for is 30 cookies + 24 cookies = 54 cookies.
Step 3: Determine how many packets of cookies Amanda needs to buy.
Since each packet contains 20 cookies, Amanda needs to buy 54 cookies ÷ 20 cookies/packet = 2.7 packets.
Since Amanda can't buy a fraction of a packet, she needs to round up to the nearest whole number.
So, Amanda should buy 3 packets of cookies.
