On a different day Mr. Flores had a customer come in and purchase 3 keyboards but returned 5 Guitar
tuners. His total was $697.75. Later that day he had
someone come in and purchase 6 keyboards and 2
Guitar tuners with a total value of $1,704.50. HINT: Let
k= cost of a keyboard and g= cost of a guitar tuner.

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.
