Complete the list of five different integers so that they have a mean of −10. explain how you found your answer. −10, 0, , −5, −15

If five numbers have a mean of -10 it means they'll have a sum of 5(-10) = -50.  

That's because the mean is the sum divided by the count, so the sum is the mean times the count.

Here our sum is -10 + 0 + -5 + -15 = -30, so our fifth number must be -50 - -30 = -20 to make the sum -50 and the mean -10.

-20

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
