Answer 1

The correct answer is

|m - 35| = 10

Step-by-step explanation:

The question wants us to determine how $35 plus or minus $10 could be witten.

The correct answer is

|m - 35| = 10

Because this has two different answers. It can be:

m - 35 = 10

So that

m = 10 + 35

= 45

OR

-(m - 35) = 10

-m + 35 = 10

-m = 10 - 35

-m = -25

m=25

Which are the two possible amount he has.
