Question

A museum has a 1/2 ounce piece of a precious metal. When the museum first received the piece, it had a value of $90. Its value has since decreased by 20%. What is the current value per ounce of the piece of metal?

A:$72.00
B: $144.00
C: $36.00
D: $180.00

Answer 1

Current value = 90 - ( 90 * 12%)
= 90 - ( 90 * 0.12 )
= 90 - ( 10.8)
= 79.2
