Using the probability (conditional) formula, where P is equals to the number of favorable outcomes over the total number of outcomes. Calculating using five and the thirty percent, 1.5 is the answer. But that cannot be the answer.
So we look for the probability using this formula derived from the original, (total outcomes) x (percentage) = (favorable outcomes), 5x=2. That gives us the answer of 0.4 or 40%.
Let's have a look:
2(4)= 8 (this would not work)
5(4)= 20 (this wouldn't work)
7(4)= 28 This does, let's check the others.
7(6)= 42 This does not work.
"D" would be the correct answer.
I hope this helps!

Okay so each person is $12
Then you need to times that for how many people are in the car x.
Since x is a variable and not a number it can go right next to the 12
You answer should be 12x
Answer:
10,000
Step-by-step explanation:
Let expenditure be 3x and Saving be 2x.
So,
3x + 2x = 2500
5x = 2500
x = 2500/5
x = 500
So,
Expenditure = 3x = 3 × 500 = 1,500
Saving = 2x = 2 × 500 = 10,00
400 students attend Washington Middle School because 400*0.8=320. Therefore 320 students is 80% of 400 students.
