Answer:
12
Step-by-step explanation:
There are many ways to approach this problem. I like a method that uses the least amount of computation. We could figure how much Wendy makes on a bag of chips, the additional amount Wendy wants to make, then divide the latter by the former to find the number of additional bags to sell.
We could use a proportion to figure the number of bags corresponding to $126 in earnings, then subtract the 72 bags already sold. Essentially, we will do this, but without the intermediate numbers.
__
The additional fraction of 72 bags will be ...
(126/108) -1 = 18/108 = 1/6
Then Wendy must sell an additional ...
(1/6)×(72 bags) = 12 bags
to increase her earnings to $126.

Answer:
5 minutes
Step-by-step explanation:
To get the response to this question, it would be required to convert both times to seconds alone.
For the first, the time It takes to flash is 1 minute 15 seconds which is same as 75 seconds
For the second, it takes 1 minute 40 seconds which is same as 100 seconds.
Now to get the time they would flash together, we need to know their lowest common multiples. The values involved are 75 and 100. Thus, the lowest common multiple of both is 300.
This is equivalent to 300 seconds which is 5 minutes time
