An engineer performs a flow test of a cooling water system. The test equipment hooks into flow elements in the system. There are 32 flow elements. For each flow element she needs two 3 feet lengths of polyflow tubing with quick release connectors on each end. Both lengths of polyflow 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 feet 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?

Each flow element requires a test gauge ---> 32*80 = $2560

Each flow element needs total of 6 feet of tubing  ----> 32*6 = 192 ft
price per foot = 6/100 = $.06
-----> 192*.06 = $11.52

Each 3-ft length of tubing requires 2 connectors. ----> (192/3)*2 = 128
-----> 128*2.5 = $320

Total Cost = 2560 + 11.52 + 320 = $2891.52

Subtract from budget:
3000 - 2891.52 = $108.48
