I think it should be x(ax +b) + c. Not sure though.
Marisa had rounded 3.48 to 4 and times it to 7.33 which she rounded to 8
In fact 3.48 is closer to 3 we know this since the .48 of 3.48 s below .50 if it was .50 or above it would round to 4 but it doesn't the same applies to 7.33 so
it should be 3 x 7 = 21
This is pretty much 75% of 55.5 which is 41.625. Rounding that up would make $41.63.
It has to be greater than the difference between the two sides, so 97-14=83
