8+t/2

Yeah number three seems correct

2. Sum is addition so yes, it it (8+t)/2

3. You are correct again in 3, although the problem is a little unclear if the whole of (8/y-3) is multiplied by x or just the three, but i think your answer is the best bet

the first one looks like this:

x*0.9 = 46.98 then solve for x

x= $52.20

OR.

x- (x*0.1)= 46.98 solve for x

x=$52.20 the first one is easier

Your answers for the 2 and 3, seem to be correct.
