Therefore, the answer is 1) y = 2x - 6
Answer: (C) $104
<u>Step-by-step explanation:</u>
The Annual Expenses are:
- Car Insurance = $850
- <u> Books </u>= <u>$400 </u>
Total = $1250
There are 12 months in a year so divide the Annual Expense by 12:
<u> 1 0 4</u>
12 ) 1250
<u> -12↓↓ </u>
5↓
<u> - 0↓ </u>
50
<u> - 48 </u>
2 ← The remainder is less than one-half so don't round up
