An engineer performs a flow test of a cooling water system. there are 32 flow elements. for each flow element she needs two 3 feet lengths of poly flow tubing with quick release connectors on each end. both lengths of poly flow tubing plug into a test gauge to measure the flow across each flow element. each test gauge is $80. the 3/16” polyflow tubing is $6.00 for 100 ft. the connectors are $2.50 each. the budget for the test is $3,000.00. after buying the necessary equipment, how much under budget should she be?
