Because they all have the same denominator, all you have to do is add the numerator! So, 3/k + 4/k would equal 7/k

I need so much help please somebody help me

marysya [2.9K]

Answer:

$448

Step-by-step explanation:

You need to find 2% of 400.00, so you would do this: 0.02 · 400 = 8

That means $8 is 2% of 400, so all you need to do is multiply 8 by 6 to get 48. Add that number to the original $400, and you get $448.
