Answer 1

Answer:

Hence, the system of inequality is:

x+y≥12

 x≥6

2x+4y≤20

Step-by-step explanation:

Let he buys x mango and y apples.

Amount purchased at least 12 pieces.

This means that:

x+y≥12

Mango bought at least 6 pieces.

i.e.

x≥6

Mango price Rs 2 per fruit and apple Rs 4, per fruit. He has Rs.20.

That means the inequality is:

2x+4y≤20

Hence, the system of inequality is:

x+y≥12

 x≥6

2x+4y≤20
