The total amount of money (in cents) in x nickels, (x+5) dimes and 2x quarters
Scorpion4ik [409]

\\
\text{Suppose you have x nickels, (x+5) dimes and 2x quarters}\\
\\
\text{we know that the value of 1 quarter is}=\$ 0.25=\text{ 25 cents}\\
\\
\text{value of 1 dime}=\$0.10=10 \text{ cents}\\
\\
\text{value of 1 Nickel}=\$ 0.05=5 \text{ cents}\\
\\
\text{so the total amount of money in cents is}\\
\\
=5(x)+10(x+5)+25(2x)\\
\\
=5x+10x+50+50x\\
\\
=65x+50

So the total amount of money is: (65 x +50 ) cents
