Answer:
The odds of the event happening = 7:3
Step-by-step explanation:
Given
Probability of an event happening = 70%
To find the odds of the event happening.
Solution:
Odds of an event happening is the ratio of the probability of the event happening and the probability of the event not happening.
Probability of the event not happening will be = 
So, the ratio of the probabilities of event happening and not happening can be given as:
⇒ 
⇒
[Representing percent in fraction form]
⇒
[Replacing division sign with multiplication sign by taking reciprocal of divisor.]
⇒
[Canceling out the common terms]
⇒
[Reducing fraction to simplest form]
Thus, odds of the event happening is = 
Answer:

Have x = the number of hours rented
so in order to find when they would be the same, set both equations equal to each other
27.50x=23.25x+17
first subtract the smaller (x) amount from the larger (x) amount
27.5x-23.25x=4.25x
4.25x=17
divide both sides by 4.25
x=4
after 4 hours would the rentals cost from both shops be the same
