Question

meagan has $1.10 in dimes nickels and pennies she has three times as many nickels as pennies and the number of dimes is two less than the number of pennies how many dimes nickels and pennies dose she have please help

Answer 1

x = pennies

3x = nickels

x-2 = dimes

0.01x + 0.05(3x) + 0.10(x-2) = 1.10

0.01x + 0.15x + 0.10x - 0.20 = 1.10

0.26x-0.20 = 1.10

0.26x = 1.30

x = 1.30 / 0.26 = 5

5 pennies
5-2 = 3 dimes
3*5 = 15 nickels

check: 5 pennies = 0.05, 3 dimes = 0.30, 15 nickels = 0.75
0.75 + 0.30 + 0.05 = 1.10

pennies = 5
nickels = 15
dimes = 3
