Diahann mowed his next-door neighbor’s lawn for a handful of dimes and nickels, 80 coins in all. Upon completing the job, he counted out the coins and it came to $6.60. Which system of equations could be used to find the exact number of dimes and nickels?

Options

d + n = 6.60；0.10d + 0.05n = 80

d + n = 80；d + n = 6.60

d + n = 80；0.10d + 0.05n = 6.60

d + n = 80；0.05d + 0.10n = 6.60
