Defined Variable: Let \( d \) represent the number of days Jack can use the golf balls.
Inequality: Jack starts with 50 golf balls and uses up to 30 golf balls each day. We can express this situation with the following inequality: \[ 50 - 30d \geq 0 \]
Inverse Operations to Solve:
-
Start by isolating the term with \( d \): \[ 50 \geq 30d \]
-
Divide both sides by 30: \[ \frac{50}{30} \geq d \]
-
Simplify the fraction: \[ \frac{5}{3} \geq d \] or \[ d \leq \frac{5}{3} \]
Final Solution with Units: The maximum number of whole days Jack can use the golf balls is: \[ d = 1 \text{ day} \]
So, Jack will run out of golf balls after 1 day of using the maximum allowed golf balls (30 per day).
