Amy loaned $5 to each of 20 people. she recorded each loan by writing -5$in her bank book. what is the total change in the amount of money amy had before the loans?

The change in the amount is -100.

Step-by-step explanation:

Let x be the original amount Amy had,

Since, She loaned $5 to each of 20 people.

⇒ Total loan she gave  = 5 × 20 = $ 100

Thus, her final amount =  Original amount - The amount of loan she gave

= x - 100,

Hence, the total change in the amount = Final amount - Original amount

= x - 100 - x

= -100

⇒ The change in the amount is -100.
