Answer:
$234
Explanation:
To determine the total amount, we need to multiply the number of pieces by their respective values and then add the results.
For the 380 pieces of 50 cents, we have:
380 * $0.50 = $190
And for the 220 pieces of 20 cents, we have:
220 * $0.20 = $44
Adding the results, we get:
$190 + $44 = $234
Therefore, the total amount of 380 pieces of 50 cents and 220 pieces of 20 cents is $234.
