Answer: 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.
