At a store, you are given a 20% discount and you pay a 7% sales tax. does it matter which is calculated first?

Yes because you would pay less if the 20% was taken off first because it would be a lower amount since your taking a percent of the whole total and not combining the two

The full question isn’t shown. part of it is cut off

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.
