Question

Jim sells mobile phones and tablets. Jim must earn at least $3,000 per month. He earns $30 profit for each mobile phone and

$50 profit for each tablet. He has space in his inventory for only 100 total items and must have at least 20 tablets. Let u
represent the number of mobile phones Jim sells and y represent the number of tablets Jim sells.
Which system of linear inequalities represents the solution set to Jim's situation?

Answer 1

Explanation:

Number of tablets should be at least 20 which means it should ≥ 20

y ≥ 20

Jim should earn at least $ 3000

30u + 50y ≥ 3000

The linear inequalities are:

y ≥ 20

30u + 50y ≥ 3000
