the rent during the past year amounted to $2700 per year. His rent was 20% of his income. Find his income for the last year.

Question

• 2700
• 20%

Answer 1

The whole idea is to test your understanding of percentages

 

ALWAYS convert percentages in to decimals right away by dividing the percentage by 100.

 

In this case you have 0.20 (20/100)

 

Whatever the income is, which you don't know yet, when multiplied by 0.20, will give you the amount he paid for rent.

 

Now call the income X and you will have

 

0.20X=2,700

 

=> X = 2700/0.02

 

hope this helps
