Answer:

Reliability

#The test results 110 1nd 150 are between 27% and 36% depending on which direction you take. That variation is wide apart and the test can't be considered reliable.

Multiply thru the Quantity Equation by 15
Multiply thru the Value Equation by 10.

15h + 15s = 15*87
15h + 5s = 785</span>Subtract and solve for "s":<span>10s = 520

Solve for h:
h + s = 87
h + 52 = 87
h = 35 (# of hot dog's sold)</span>
