Which balance is $86 more than the balance of -$47.90? a. $38.10 b. $-13.90 c. -$47.90 d. -$133.90. show me how you solved it. and does it make sense?

Option: A is the correct answer.

              A.   $38.10

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

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.
