Answer: a. B-4
b. 12xf (or just 12f)
c. s+8
Explanation: a. the points that the Bulls scored is represented by B so if it's four points less you get B minus 4
b. the number of feet is represented by the letter f so if it's 12 times the number of feet then it's 12 times f
c. the total cost of the shirt is represented by the letter s and since it's the total cost you know you're adding so you get s+8 because the pair of socks is $8.
*Also - I think the last part on 3 where it says "the expression is" is not only 4 but instead 4g
Hope this helped! :)
