Question

Yuson must complete 210 minutes of community service. She does 30 minutes each day. Which linear equation represents the number of minutes Yuson has left after X days?

A) y = 210x - 30
B) y = 30x - 210
C) y = 30x + 210
D) y = 210 - 30x

Answer 1

The linear equation that represents the number of minutes Yuson has left after X days is y = 210 - 30x.

Step-by-step explanation:

To find the linear equation that represents the number of minutes Yuson has left after X days, we need to consider the total amount of community service she needs to complete and the time she spends each day. Since Yuson needs to complete 210 minutes of community service and does 30 minutes each day, the equation can be represented as y = 210 - 30x, where y represents the number of minutes Yuson has left and x represents the number of days.
