Performing the multiplication, we find that 60 ÷ 3 = 20 elves quit in the first round.

Nissa hires 60 seasonal workers to play elves in her department store's Santa village. A third of the elves quit after children vomit on them, then 10 of the remaining elves quit after kids kick their shins. How many elves are left?

Answer: 30 elves are left.

Nissa initially hires 60 seasonal workers to play elves. This is our starting number of elves.

A third of the elves quit after children vomit on them. To find this number, we multiply the total number of elves by $\frac{1}{3}$ .

Performing the multiplication, we find that $60 \div 3 = 20$ elves quit in the first round.

To find out how many elves are left after the first group quits, we subtract the number of elves who quit from the initial number of elves.

After $20$ elves quit from the initial $60$ , there are $60 - 20 = 40$ elves remaining.

From the remaining elves, an additional 10 elves quit after kids kick their shins. This is a fixed number given in the problem.

To find the final number of elves left, we subtract the second group of quitters from the elves remaining after the first group quit.

Subtracting $10$ from $40$ , we find that $30$ elves are left.
