Problema Solution
stephanie bought between 2 and 6 bags of potting soil for her flowers. The soil cost $2.79 a bag. What was the total cost of the potting soil?
Answer provided by our tutors
let 'x' be the total number of begs she bought
2 <= x <= 4
the total cost of x bags of soil is x*2.79
and also we have
2*2.79 <= x*2.79 <= 4*2.79
5.58 <= x*2.79 <= 11.16
the total cost of the potting soil is between $5.58 and $11.16.
