1- The answer is that she wants the new time to be 32 minutes

Solution: The question asks that she wants to DECREASE by 20%

What you will do it convert 20% to a decimal (which is 0.20)

Then, you need to multiply the minutes by the decimal:

40 x 0.20 = 8 minutes

Now you know that 8 minutes will be 20% of 40 minutes, so you just subtract 8 from 40 UwU
