Chapter 13, Problem 13.27E

I need guidance with this general accounting problem using the right accounting principles.

Fairview Industries recently purchased 128,000 units of raw material for $576,000. Four units of raw materials are budgeted for use in each finished good manufactured, with the raw material standard set at $24.00 for each completed product. Fairview manufactured 31,250 finished units during the period just ended and used 127,500 units of raw material. If management is concerned about the timely reporting of variances in an effort to improve cost control and bottom-line performance, what would the materials purchase price variance be? Need help

Please provide the accurate answer to this general accounting problem using appropriate methods.
