Question

Sierra and Charlie are paid $12 per hour.  However, this week Charlie received a $40 bonus.  Given that S and C represent the number of hours worked by Sierra (S) and Charlie (C), which expression can be used to represent their combined earnings for this week?

GPT 3.5 · Answer

Sierra's earnings for this week would be given by $12 times the number of hours worked, S. Therefore, Sierra's earnings would be $12S. Charlie's earnings for this week would be given by $12 times the number of hours worked, C, plus the $40 bonus. Therefore, Charlie's earnings would be $12C + $40. Finally, their combined earnings for this week would be equal to Sierra's earnings plus Charlie's earnings, which is $12S + $12C + $40.
