    500-200=300
2)300/100=3 на 1%
   3*60=180 сниж
   300-180=120

Answer 3

Calculating Remaining Money After Spending 40% and 60% of the Remaining Amount

To calculate the remaining money after spending 40% of the initial amount and then 60% of the remaining amount, we can follow these steps:

1. Calculate the amount spent initially: 40% of 500 rubles = 0.4 * 500 = 200 rubles. 2. Calculate the remaining amount after the initial spending: 500 - 200 = 300 rubles. 3. Calculate the amount spent from the remaining amount: 60% of 300 rubles = 0.6 * 300 = 180 rubles. 4. Calculate the final remaining amount: 300 - 180 = 120 rubles.

So, after spending 40% of the initial amount and then 60% of the remaining amount, 120 rubles are left.
