First you have to 8.50 by 6 because there are 6 teachers and admission for each teacher is 8.50. So that is equal to 51. Then you subtract 51 from 250 because you have to know, about how much money left after teachers paid for them selves. So 250-51=199. Then you have to divide 199 by 6 so you know how much students can go there and 199/6=33 and 1/6. So basically 33 students can go there.
It’s the 3rd one I believe

Answer:
<u>16 ounces</u> of the 30% hydrochloric acid solution is used in order to obtain the 25% solution.
Step-by-step explanation:
Let amount of 30% ounces be 'x' and that of 15% ounces by 'y'.
Given:
Total amount on mixing both the solution = 24 oz
∴
Also, the total acid content in the resulting 25% solution is equal to the sum of the acid contents in 30% and 15% solutions.
∴
Now, plug in 'x' from equation (1) into equation (2). This gives,
ounces
Therefore, ounces
Hence, 16 ounces of the 30% hydrochloric acid solution is used in order to obtain the 25% solution
