Sherrie borrowed money from her parents to buy a new phone. The amount she owes them in dollars can be represented by the integer . Sherrie also did some babysitting this month. The amount of money she made in dollars can be represented by the integer . If Sherrie had no other income or expenses, which integer represents her total worth in dollars?

Respuesta :

To find the integer that represents her total worth, add the integers that represent her debt and that of her income:

[tex]-88+145[/tex]

The expression can be rearranged by commutativity as:

[tex]145-88[/tex]

Find the difference:

[tex]57[/tex]

Since this is a positive number, it can be written as:

[tex]+57[/tex]

Hence, the fourth option is the correct answer.
