The price of a pair of shoes is $28. the sales tax rate is 2.39 percent. what is the total amount you would pay if you bought these shoes?

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

the football players are volunteering for the test.
