You have $3.70 in dimes and quarters. You have 5 more quarters than dimes. How many of each coin do you have
let dimes be d and quarters q
if you have 5 more quarters than dimes, then q=d%2B5
if you have $ for q
3.70=0.25%2A%28d%2B5%29%2B0.10d%7D+%7D%7D%0D%0A%0D%0A%7B%7B%7B3.70=0.25d%2B0.25%2A5%2B0.10d
3.70=0.35d%2B1.25
3.70-1.25=0.35d
2.45=0.35d
2.45%2F0.35=d
highlight%28d=7%29
q=d%2B5
q=7%2B5=> $0.10%2A7=0.70
highlight%28q=12%29 =>$0.25%2A12=3 => together $3.70
