12t+10f+50. The t represents the $12 per student ticket. And the f represents the $10 per student for food

There are 5 + 1 = 6 terms in the binomial expansion of (1−0.02)5, and since the 4th term is approximately 0, the 5th and 6th terms are also approximately 0. So, approximate the value of 0.985 by adding the first three terms: 1 + (-0.1) + 0.004 = 0.904.
the number changes by the degree so you need to multiply it.
