Comparing wind chills. Use the formula from Exercise 107 to determine who will feel colder: a person in Minneapolis at 10°F with a 15-mph wind or a person in Chicago at 20°F with a 25-mph wind.

(this is the formula from exercise 107)

W=91.4 -(10.5+6.7(radical symbol)v-0.45v)(457-5t)/110

In the above formula I have written radical symbol in place of a radical symbol and a forward slash (/) for division. The entire formula is divided by 110. The small - means negative in front of the parentheses and in front of the 0.45v as well as the -5t.
