Explanation:

I was planning a backyard barbecue and needed to buy enough burgers for 12 guests, each wanting 2 burgers. I also had to account for 10% extra in case of second helpings. First, I calculated the base number of burgers needed, then added the 10% buffer. I used basic multiplication and percentage calculation math skills to avoid buying too few or too much food.

Answer:

Last summer, I wanted to host a backyard barbecue for 12 friends, and each person told me they’d want at least 2 hamburgers. I also wanted to buy 10% extra burgers to cover anyone who wanted a second helping or any unexpected drop-ins.

First, I calculated the minimum number of burgers needed: $12 \times 2 = 24$. Then I found 10% of 24 to get the extra amount: $24 \times 0.10 = 2.4$, which I rounded up to 3 to ensure I had enough. Finally, I added the two numbers together: $24 + 3 = 27$. I bought 27 burgers, and everyone had enough to eat with a few left over just in case. The math skills I used were basic multiplication, percentage calculation, and rounding.
