Question

1. The monthly rent (1) for an office place is directly proportional to the size of the office

(a) if a 420 sq foot office rents for 12, 600 pesos per month, then what is the rent for a
900 sq foot office?​

Answer 1

1 = k x a
12600 = k x 420 divide 420 each side
30 = k
1 = 30 x 900

27,000 = monthly rent for 900 sq foot office
