I I earn 20 dollars every 7 days how many days would it take for me to get 400

Answer 1

To calculate the number of days it would take for you to earn $400, you can set up a proportion.

Let's represent the number of days it would take as "x".

Proportion: (20 dollars / 7 days) = (400 dollars / x days)

Cross-multiplying:
20x = 7 * 400

Simplifying:
20x = 2800

Dividing by 20 on both sides:
x = 2800 / 20

Calculating:
x = 140

Therefore, it would take you 140 days to earn $400.
