Awhile back, either james borrowed $12 from his friend rita or she borrowed $12 from him, but he can’t quite remember which. either way, he is planning to pay her back or ask that she pay him back this afternoon. if he has $42.80 in his wallet, which equation represents the amounts of money he may have after he sees rita?
a. |x – 42.80| = 12
b. |x + 42.80| = 12
c. |x – 12| = 42.80
d. |x + 12| = 42.80

First option is correct.

Step-by-step explanation:

Let amounts of money James may have after he sees Rita be x.

It is given that either James borrowed $12 from his friend Rita or she borrowed $12 from him.

So meeting Rita second time either he will $12 or he will receive $12.

The amounts of money James may have after second meeting with Rita is:

Case 1: If he pays $12.

            .... (1)

Case 1: If he receives $12.

          .... (2)

On combining equation (1) and (2), we get

Subtract 42.80 from both sides.

It can be written as

Therefore first option is correct.

A. |x – 42.80| = 12

Step-by-step explanation:

Given,

The initial amount in Jame's wallet = $ 42.80,

Let x represents the final amount in Jame's  wallet after seeing Rita,

According to the question,

Either he will borrow $ 12 from Rita or Rita will borrow $ 12 from him,

When he borrows $ 12 from Rita,

Final amount in the wallet = initial amount + borrowed amount

⇒ x = 42.80 + 12

⇒ x - 42.80 = 12  (1)

While, when Rita  borrows $ 12 from him,

Final amount in the wallet = initial amount - borrowed amount

⇒ x = 42.80 - 12

⇒ x - 42.80 = -12

⇒ -(x - 42.80) = 12 (2),

By combining equation (1) and (2),

We get,

| x-42.80 | = 12

Which is the required equation.

⇒ Option A is correct.
