Let s be the original price of the shoes.
Now s - (s*.30) can be used the find the original price since s times .30 will give you 30% of the original price and if you subtract that from the original price it will give you what 30% off is.

The statistical question would be B.
Answer:
E = (1, 2)
Step-by-step explanation:
You want ...
(E -G) : (O -E) = 3 : 4
4(E -G) = 3(O -E) . . . . . . . . "cross multiply"
4E -4G = 3O -3E . . . . . . . . eliminate parentheses
7E = 4G + 3O . . . . . . . . . . . add 3E+4G
E = (4G +3O)/7 . . . . . . . . . .divide by 7
E = (4(-5, -1) +3(9, 6))/7 = (-20+27, -4+18)/7 = (7, 14)/7 . . . . fill in G and O
E = (1, 2)

Answer:20x+50= 5x+70
Step-by-step explanation:
x = number of cavities
use the subtraction property of equality and solve for x
20x+50 = 5x+70
-5x -50 -5x - 50
15x = 20
Then you divide 20 by 15
15x = 20
----- -----
15 15
x= 4/3
