12.

The answer would most likely be 5.11 or 11.5
Answer:
FALSE
Step-by-step explanation:
If y varies inversely as x., this is expressed as;
y = k/x
k is the proportionality constant
when y = 3 and x = 4
3 = k/4
k = 3 * 4
k = 12
when x = 15;
y = k/x
y =12/15
y = 4/5
Hence y is not equal to 12 when x = 15.
The correct answer is FALSE
76.15 - 43.49 = 32.66
It costed him $32.66 to make the homemade jewelry.
