Lunch cost $4.14 and she got $5.86
Answer:
A quick way to calculate upper and lower bands is to halve the degree of accuracy specified, then add this to the rounded value for the upper bound and subtract it from the rounded value for the lower bound.
You multiply 2(x+1) which is 2x+2.
Then you multiply 5(2x-3) which is 10x-15
Finally, you add 2x+2 and 10x-15, and you get 12x-13
The answer is 12x - 13
