x =
$4.55
$0.65
x = 7
Solving for the other unknowns:
2x = 2(7)
2x = 14
x + 5 = 7 + 5
x + 5 = 12
Answers:
Number of Nickels = 7
Number of Dimes
= 12
Number of Quarters = 14
Step 5.
The number of quarters is twice the number of
nickels.
2(7) = 14
The number of dimes is five more than the number
of nickels.
7 + 5 = 12
The total value is $5.05.
7($0.05) + 12($0.10) + 14($0.25) =
$0.35 + $1.20 + $3.50 = $5.05
Thus, the answers check.
