Answer 3

Calculating Remaining Percentage of Money

To calculate the percentage of money remaining after spending 540 rubles out of 1350 rubles, we can use the following formula:

Percentage Remaining = ((Amount Remaining) / (Initial Amount)) * 100

Substituting the given values: Percentage Remaining = ((1350 - 540) / 1350) * 100

Calculation

Using the formula: Percentage Remaining = ((810) / 1350) * 100

Percentage Remaining = (0.6) * 100

Percentage Remaining = 60%

So, after spending 540 rubles out of 1350 rubles, your mom has 60% of the money remaining.
