We need to multiply Y by 3 since it says "3 times the number".
3Y; next we need to add 4 since it says 4 more.
3y+4; the reason I knew to put it in this order is because it said 4 more than 3 times, which means you add 4 after you multiply.
The expression is 3Y+4

8)A again for the same reason as number 7
