Step-by-step explanation:
the correct answer is c
7 is 1/4 of 28, so 7 is 25% of 28.
The drop from 28 to 7 is a drop of 21.
21 is 3 times 7, so 21 is 3 times 25%.
Answer: It is a 75% decrease.
The answer is C) 24.
24 + 19 = 43.
43 - 24 = 19.
Number of red cars = x
Number of white cars = y
x + y = 75
y + 3 = 2x
x + y = 75
y = 75 - x
(75 - x) + 3 = 2x
78 = 3x
26 = x
y + 3 = 2(26)
y + 3 = 52
y = 49
There are 49 white cars.
