Problem 2

In a cooperative video game, the gold collected on a mission is shared evenly between the 2 players. To afford the next upgrade, Andre’s character needs 20 gold. Andre only has 6 gold right now.

Let $g$ represent the amount of gold the 2 players will collect on the next mission. Write an inequality that represents the condition that Andre gets enough gold to buy the upgrade.

Show Solution
Solution
$\frac{1}{2}g + 6 \geq 20$ or equivalent
