In Dualia, citizens pay for goods using only one-dollar bills, two-dollar bills and four-dollar bills. How many ways are there for a citizen to pay for an antique abacus that costs 2017 dollars using one or more of these three denominations

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.

Any pictures or something i need more info
