Answer:

1.) ₱3 499.99

2.) 2.1433 hectares

3.) 2.9275 hectares

Step-by-step explanation:

1.) n - ₱500 = ₱2 999.99

n = ₱500 + ₱2 999.99

n = ₱ 3 499.99

Therefore ₱3 499.99 is the price of microwave before its sale.

2.) 15 - 12.8567 = n

n = 2.1433

Therefore the banana plantation is much bigger then the sugarcane plantation by 2.1433 hectares.

3.) 5 - 2.0725 = n

n = 2.9275

Therefore Mang Juan owns 2.9275 hectares of land now.
