solong [7]

Answer:

Step-by-step explanation:

18,000 is what percent of 120,000

18,000 = x%(120,000)

18,000 = 120,000%x

18,000 = 1200x

18,000/1200 = x

15% = x <===

what percent would 48,000 down payment be

48,000 is what percent of 120,000

48,000 = x%(120,000)

48,000 = 120,000%x

48,000 = 1200x
