Answer:
$40.00
Step-by-step explanation:
I just multiplied 0.30 by each of the listed choices, and subtracted the answer from the choice. I found out that 40 x 0.30 = 12. After that, I subtracted 12 from 40, and got 28! I KNOW THIS IS A LONGER WAY TO FIND THE ANSWER,SORRY!
$40
(1 - 0.30)x = 28
x = 28/(1 - 0.30)
x = 40
original price = $40
5%
36.10 + 1.90 = 38
1.9 / 38 = 0.05
0.05 x 100 = 5
mean=sum of data/no of data
=12/3
=4
therefore mean=4
-24
20-(-20)+16
More steps
20 - 5*-4 + 2*8
12
3 x 4
if its one unit then you just multiply the sides in this case 3 x 4
