Respuesta :

you would add $86 plus $47.90

Answer:

Option: A is the correct answer.

              A.   $38.10

Step-by-step explanation:

We are asked to find the balance which is  $86 more than the balance of -$47.90.

i.e. the balance is:

$ 86+ (-$ 47.90)=$ (86-47.90)

( since, we know that on opening the parentheses term if the sign before the parentheses is negative then the terms come out with opposite sign and the terms remains the same if the sign is positive )

which on simplifying we have:

            =   $ 38.10
