Find out how much money one woman would pay a year by multiplying $140 and 12 months together like this.
140×12=1680
Next, find out how much she'd be paying for 20 years by multiplying the product by the years like this.
1680×20=33600
Now, to find out how much money all 1000 women are paying for the 20 years, multiply the previous product with the number of women.
33600×1000=3600000
Therefore, all 1000 women would be paying $3,600,000 total during the 20 year time period.
HOPE THIS HELPS!
