Answer:
The length of the copy of the dollar bill is 4.88 inches in length and 2.08 inches in width.
Explanation:
If Dani wants to make a smaller copy of a dollar bill and reduce its size to 80%, you will need to multiply the dollar bills original length by 8%.
80% = 0.8
0.8 x 6.1 = 4.88
80% = 0.8
0.8 x 2.6 = 2.08
