Luis makes $23.10 per hour at his job for the first 40 hours he works each week. if he works more than 40 hours, then luis makes $34.65 per hour. if luis works 46 hours in one week, how much does he earn?
a. $1,062.60 b. $1,097.25 c. $1,131.90 d. $1,593.90

The answer is c. $1,131.90. Let x be the rate for the first 40 hours: x = 23.10 dollars per hour. Let y be the rate for each hour after first 40 hours: y = 34.65 dollars per hour. If Luis works 46 hours in one week, he will earn: 40x + 6y = 40 * 23.10 + 6 * 34.65 = 924.00 + 207.90 = 1,131.90.
