Direct variation can be written as a proportion. Therefore, we can write:
Cross multiply to get:
4y=40
Divide by 4 on both sides to get that
y=10.

To work out the mean, add them all up and divide by however many values there are:
(18+54+42+(76x2)+46) / 6 = 52
To work out the median, order them from largest to smallest or vice versa and find the middlest value.
18, 42, 46, 54, 76 ,76
(46 + 54) / 2 = 50
The mode is the most frequently occurring number, so it would be 76.

Whenever they ask what is a certain fraction of a number, just multiply.
(3/4)(535)=401.25
Answer:
7 Days
Step-by-step explanation:
Miles cost:
$0.10 * 200 = $20
Daily Cost
Her budget at this point is $330 because $350 - $20 (the miles)
$330 / 42.72 = Roughly 7.72
Therefore Zoey can drive for 7 days before her budget runs out.
It’s a good step because you know where you are at in present time as well as looking ahead into the future financially.
