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