Mary is paid $600 a month on her regular job. During July in addition to her regular job, she makes $400 from a second job. Approximately what percentage of her annual income does Mary make in July? Assume Mary has no other income except the income mentioned above.
1. 8
2. 8 1/3
3. 12 1/2
4. 13
Mary makes $600 a month on her regular job. Therefore, she receives $600 .12 = $7,200 a year from her regular job. Her only other income is $7,600. She makes $600 + $400 = $1,000 during July, so she makes 1,000/7,600 = 5/38 which is about .13 of her annual income during July. Therefore, Mary makes about 13% of her annual income in July.
