Students need at least 75 hours of volunteer service to meet their graduation requirement. Samir has already completed 48 hours. Write and solve an inequality to determine how many more hours he needs to complete.

R is the amount of hours remaining to complete the requirement

R + 48 ≥ 75

Subtract 48 from both sides of the equation:

R ≥ 27

He has to complete an amount of hours greater than or equal to 27

A variable, so I will use the variable X then your hours completed which is 48, so it looks like (X + 48) now we have to compare it to how many hours he needs to do. Because it says at least we use the sign, Now the equation is X + 48 75.

X + 48 75
