The number of grams of gold you can purchase for $15 if Gold cost $8.00 per ounce is 53.26g
Dimensional analysis is a means of representing values using units.
From the question, we are told that Gold cost $8.00 per ounce, this means that:
$8.00 = 1 ounce
In order to calculate the amount in grams you can purchase for $15, we need to know the price in ounces first.
$15.00 = x
Divide both expressions
Next is to convert the ounces to pounds.
1 pound = 16 ounces
y = 1.875 ounces
y = 1.875/16
y = 0.1171875 pounds
Conver 0.1171875 pounds to kg
Since 1kg = 2.2 pounds
z = 0.1171875 pounds
2.2z = 0.1171875
z = 0.1171875/2.2
z = 0.053267kg
Finally, convert 0.053267kg to grams using the conversion rate
1kg = 1000g
0.053267kg = y
y = 0.05326 * 1000
y = 53.26g
This shows that the amount of grams you can purchase for $15 is 53.26g
