Answer:
Two coins are "1 half dollar" and "1 nickel".
Step-by-step explanation:
It is given that we have two US coins that total $0.55.
We know that
1 penny = 1 cent = $0.01
1 nickel = 5 cents = $0.05
1 dime = 10 cents = $0.10
1 quarter = 25 cents = $0.25
half dollar = 50 cents = $0.50
1 dollar = 100 cents = $1
The given amount can be divide into two parts.
$0.55 = $0.50 + $0.05
$0.55 = 1 half dollar + 1 nickel
Therefore, the two coins are "1 half dollar" and "1 nickel".
