Answer:
Store A and it would cost $32.40 (answer choice A)
Step-by-step explanation:
Let's start by studying how much she would pay for a single balloon on each store:
In store A: (5 balloons for $6) then per each balloon: $6/5 = $1.2 per balloon.
In store BA: (13 balloons for $16.25) then per each balloon: $16.25/13 = $1.25 per balloon.
This shows us that the better price is in store A if she wants to pay as little as possible. Now, at that price, if she wants to buy 27 balloons, she will be paying (27 times $1.2): 27 * $1.2 = $32.40
7.675 inches of rain was the total amount in the two weeks
You can see that the point has went 2 numbers backward. Which means that the power of ten that 517.23 was divided by should have 2 zeroes, which is of course 100.
The number of numbers which the point go backward is equal to the number of zeroes contained in the power of 10.
divided by 10, the point go 1 number backward; divided by 10 000 000, the point go 7 numbers backward, etc...
Hope this Helps! :)
