Complete question :

Darragh has a Golden Eagle coin in his collection with a mass of 13.551\,\text{g}13.551g13, point, 551, start text, g, end text. An uncirculated Golden Eagle coin has a mass of 13.714\,\text{g}13.714g13, point, 714, start text, g, end text. How much mass has Darragh's coin lost

0.163 g

Step-by-step explanation:

Mass of golden eagle coin = 13.551 g

Mass of uncirculated coin = 13.714 g

Amount of mass Darragh's coin has lost :

Thus is the difference in the mass of the Golden coin and the uncirculated con

13.714g - 13.551g

= 0.163 g

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
