George worked from 7:00 A.M. to 3:30 P.M. with a 45-minute break. If George earns $10.50 per hour and does not obtain paid for his breaks, how much will he earn? (Round to the nearest cent.)

First, ?nd the number of hours George worked. From 7:00 A.M. to 3:30 P.M. is 8 1/2 hours. Take away his 3/4 hour break and he works 7 3/4 hours. To ?nd out what George is paid, multiply the hours worked, 7.75 (modified from the fraction), through the pay per hour, $10.50; 7.75 × $10.50 = $81.375. The directions say to round to the nearest cent. Thus, the answer is $81.38.
