Answer: 4200? or 10 because there is a minus sign
Step-by-step explanation:
if we start with the parentheses you can see 4 x 15 = 60 and your subtracting 70 minus 60 so it would be 10
Step-by-step explanation:
![{c}^{2} - 7c - 4 \\ {3}^{2} - (7\times 3) - 4 \\ 9 - 21 - 4 \\- 16](https://tex.z-dn.net/?f=%20%7Bc%7D%5E%7B2%7D%20%20-%207c%20-%204%20%5C%5C%20%20%7B3%7D%5E%7B2%7D%20%20-%20%287%5Ctimes%203%29%20-%204%20%5C%5C%209%20-%2021%20-%204%20%5C%5C-%2016)
Your answer would be 36,000 because he gets 3000 every month and every month for a year he would get your answer which would be 3000×12 which equals 36,000

26/4= 6.5
So the mean of that set will be 6.5
