equation would be the start at 2.51 and go up 1
2.51 + 1x=91.52
we would start by subtracting 2.51
98.01 = x
so they drove 98.01 miles
if you were looking for time you would need the mph if the car was going around 50 it would be close to 2 hours
1. 10 boxes
2. about 20
3. 6x100 + (6x9)x10 + 6x8
2 x 4 = 8
2 x X = 2x
so 8 + 2x
