$-100

Explanation:

Answer 2

Answer: The change in the amount is -100.

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.
