Answer:
3 postcards

Explanation:
So the question says that Brenna bought 4 packs of 12 postcards, which is the same as 4x12.

4x12=48, so Brenna bought 48 postcards.

It says that she only needed 45, so we can subtract 45 from 48.

48-45=3

Brenna had three postcards left over.

Hope this helped you!

nekit [7.7K]

The maximum mortgage payment allowed for someone with an annual salary of $73.025 would be $2,190.75 per month, so the correct option is A.

<h2><u>How to determine the amount using the standard 28/36 guides?</u></h2>

To determine, using the standard 28/36 guidelines, what is the maximum mortgage payment allowed for someone with an annual salary of $73,025, the following calculation must be made:

((73025 x 36) / 100) / 12 = X
(2,628,900 / 100) / 12 = X
26,289 / 12 = X
2,190.75 = X

Therefore, the maximum mortgage payment allowed for someone with an annual salary of $73.025 would be $2,190.75 per month.
