Atotal of $4.80 consisting of dimes and quarters was collected from a soft drink vending machine. if there's one more quarter than there are dimes, find the number of dimes and the number of quarters.
a. 18 dimes; 12 quarters
b. 12 dimes; 13 quarters
c. 13 dimes; 14 quarters
d. 14 dimes; 15 quarters

Q = d + 1
4.80 = 0.10d + 0.25q
4.80 = 0.10d + 0.25 (d + 1)
4.80 = 0.10d + 0.25d + 0.25
4.55 = 0.35d
13 = d

C. 13 dimes, 14 quarters

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.
