**21.** If he travels the same distance each day for 11 days straight and on the 12th day he travels 7 miles extra. and if he traveled 91 miles in total, the total distance that he would have traveled if he hadn’t traveled those extra 7 miles would have been 91 - 7, and then to discover the average distance traveled per day you divided it by 12.

So the expression would be (91 - 7)/12 which is C**22. **If you are subtracting 1 from 5, you are taking 1 away from 5. So you get 5-1. Then you are multiplying the difference (5 - 1) by 8, so (5 - 1) *8 and then you add 15 to it. The answer is D and not A because in A you are only multiplying -1 by 8, instead of the difference. **23.** Using BODMAS (Brackets, Orders, Divide, Multiply, Add, Subtract)

You do the brackets first, so you do the 4+2 first =6

Updated equation: 2 *(36 - 4(6))

you then multiply 4 by 6 =24

Updated equation: 2 *(36 - 24)

You then subtract 24 from 36= 12

Updated equation: 2*(12)

Final answer you multiply 2 by 12 to get 24

Answer= 24 which is A in the sheet

21) C

7 miles to and from work

22) D

23) A

Use BODMAS which means Brackets, Orders, Divide, Multiply, Add, and Subtract

then just solve the rest
