Answer:
$200*L+$100*B > $5000
where L and B are the amounts of laptops and bicycles Hyun Yong donates, respectively.
Explanation:
An inequality is an algebraic expression that consists of two members separated by an inequality. The inequality can be <, ≤,>, ≥. Your solution set is the set of real numbers that satisfy it.
A first degree inequality with two unknowns is any inequality equivalent to any of these:
ax + by + c <0
ax + by + c ≤ 0
ax + by + c> 0
ax + by + c ≥ 0
In this case, the solutions are not sets of numbers, but sets of pairs of numbers. This is the type of inequality that will arise in this case.
To write the inequality, you must first determine your variables. In this case these will be the number of laptops (L) and number of bicycles (B) that hyun Yong should donate to achieve his goal.
You know that each laptop that he donates is worth $200, so $200*L (number of laptops) represents the total value Hyun Yong donates on laptops. And each bicycle that he donates is worth $100, so $100*B (number of bicycles) represents the total value Hyun Yong donates on bicycles.
Since Hyun Yong wants to donate more than $ 5000 in laptops and bicycles, the sum between the values of laptops and bicycles should be greater than $ 5000. Finally, expressing this in an inequality, you can say that:
$200*L+$100*B > $5000
where L and B are the amounts of laptops and bicycles Hyun Yong donates, respectively.
