Question

35 yuson must complete 30 hours of community service. she does 2 hours each day. which linear equation represents the hours yuson has left after $x$ days?
a $y = -2x + 30$
b $y = 2x + 30$
c $y = -2x - 30$
d $y = 2x - 30$

Explanation:

Step1: Define total & daily hours

Total service hours: $30$. Daily completed hours: $2$.

Step2: Calculate hours completed in $x$ days

Hours completed = $2x$

Step3: Find remaining hours $y$

Remaining hours = Total - Completed, so $y = 30 - 2x$

Answer:

A. $y = -2x + 30$
