Word problems - absolute value

[Goodstudent]

I need a little assistance!

A brick company guarantees to fill a contractor's order to within 5% accuracy. A contractor orders 1500 bricks. Write and solve an absolute value equation to find the maximum and minimum number of bricks guaranteed by the brick company.

I don't know how to do it! What's the formula?

Thanks for all the help.

What are the variables that should be included in the equation (that has been asked for)?

\(\displaystyle |x-1500| \ \le \ (1500)(.05) \ = \ 75\)

\(\displaystyle Hence, \ -75 \ \le \ x-1500 \ \le \ 75 \ \implies \ 1425 \ \le \ x \ \le1575\)

Hi Mr. Kahn,

that's just it, I didn't do anything because I didn't understand what formula to use to solve the word problem. The only thing I knew was 5% of 1500 was 75. that's it.
