Answer:
He has 6 nickels, 3 dimes and 11 half dollars
Step-by-step explanation:
Let x = Number of dimes then by the statements in the question we have
that the number of nickel is 2x and the number of half dollars is 5 + 2x (remember the number of nickels is twice number of dimes). Then we can set up an equation which will show the total value of $ 6.10 $ the boy has ;
x dimes have a value of 0.10 x
2x nickels have a value of 0.10 x
5+ 2x half dollar have a value of 0.50*(5 + 2x) or 2.50 + x
adding all together we have
010x + 0.10x + 2.50 + x = 6.10
solving for x gives us a value of 3.60/1.20 which equal 3 there follows the answer 3 dimes, 6 nickels and 11 half dollars
