Answer:
Question 3: d
Question 4: a
Step-by-step explanation:
Substitute the letters for the numbers that they give you.
3. 34 or D
4. A or 80
5. B or x/4
3. plug the n and x value so:
20+5(3)-1 **always do the parenthesis**
20+15-1= 35-1= 34
4. same thing as the last one:
5(4+3(4))
20+ 3(4)= 20+ 5*12= 20+60= 80
5. you divide whatever the bill is by 4
