Yuson must complete 45 hours of community service. She does 3 hours each day. Which linear equation represents the hours Yuson has left after x days?

y=45-3x

Step-by-step explanation:

we want y, which is the number of hours left. to find this, we take:

hours left=total # of hours required - hours worked/day

so:

y=45-3x

(because x could be any number: 2 days, 3 days, etc.)
