Let N be no. of nickles. Then N($.05)+3N($.10)+2N($.25)=$3.40.
Or
4 nickels = $0.20
12 dimes = $1.20
8 Quarters = $2.00
Total = $3.40
Answer:
switch sides
-g+2/5UA=5b
add g to both sides
-g+1/5UA+g=5b+g
simplify
1/5UA=5b+g
multiply both side by 5
5×1/5UA=5×5b+g
simplify
AU=25b+5g
divide both sides by U
AU/U=25b/u+5g/u =U/U=0
simplify
A=25b+5g/U
