every month. How should her yearly expenses be represented?

1. O2 + 4y + 122
2. O 2x + 4y + 12z
3. OI +y + 122
4. O 2x + 3y + 12z​

Answer 1

2x+4y+12z

Explanation:

I just did the test and got it right

Answer 2

Answer: 2x+4y+12z (choice B)

Work Shown:

x = amount of rent paid per half year

2x = amount of rent paid annually

y = amount spent on groceries per quarter

4y = amount spent on groceries annually

z = amount spent on a transit pass monthly

12z = amount spent on transit pass annually

2x+4y+12z = total amount of money spent annually
