This is a math problem. First of all, it takes 22 times 38 to be 836 yuan. Plus Mr. Cao's 38 yuan, the total is * * * 874 yuan, which is enough.

Teacher Cao showed 22 students around. Tickets to 38 yuan. Is it enough to bring 900 yuan? This is a math problem for primary school students. Similarly, four teachers from the experimental primary school led 60 students to participate in the aquarium, including adult tickets 10 yuan, children tickets for 5 yuan and a * * * 500 yuan. Do you have enough money?
