Answer:
No, it is not possible to change $15 into an equal number of half-dollars, quarters, and dimes
Step-by-step explanation:
Let there are equal number of half-dollars, quarters, and dimes
Let it be x
now, half-dollar=0.5 dollars
quarters=0.25 dollars
and dimes=0.1 dollars
0.5x+0.25x+0.1x=15
0.85x=15
x=17.6
which is not a whole number
Hence, It is not possible to change $15 into an equal number of half-dollars, quarters, and dimes
