12+40+SC

Answer 1

To represent Sierra and Charlie's combined earnings for this week, we need to consider their hourly pay and the bonus Charlie received.

• Sierra earns $12 per hour for S hours, which gives her earnings as \(12S\).
• Charlie earns $12 per hour for C hours, giving him earnings as \(12C\).
• Additionally, Charlie received a $40 bonus.

Thus, the combined earnings can be expressed as:

\[ 12S + 12C + 40 \]

So the correct expression is:

12S + 12C + 40
