$69

Step-by-step explanation: For every hour ray works over 40 hours, he makes an additional $7.50. According to part B, Ray calculated incorrectly that he earned $45 of additional pay. His error when he calculated incorrectly his overtime pay was that he didn't mulitply correctly, and that gave him the andwer of $45. So therefore, Ray's paycheck for working 46 hours was $69. How I found out my answer I did 150% times 46 which gave me 6,900. After that I divided 6,900 by 100 which gave me 69. If we wanna check our answer we can always divide 69 and 46 hours and get 150%. So In Conclusion, Ray would make more oney working 32 hours a week, and then 46 the next week. We also found this out, because working 32 hours one week ray makes $48, but when he works 46 hours a week, ray makes $69 and when adding those together it makes much more than 40 hours a week for two weeks.
