Problema Solution
In Tom's piggybank there are pennies, nickels and dimes. He has sixteen times as many nickels as dimes and fourteen times as many pennies as dimes. If the total amount of money is #35.36, what is the total amount of nickels?
Answer provided by our tutors
let dimes = x , nickels = 16x , pennys = 14x
0.1x + 0.05*16x + 0.01*14x = 35.36
0.1x + 0.8x + 0.14x = 35.36
1.04x = 35.36
x = 34
total amout of nickels = 16*0.05*34 = $27.20
