please help me find the fixed cost with the high low method

a. Are the fixed costs and variable costs per unit the same for private and public universities? Include in your answer the equation for both the private and public universities. The fixed and variable between private and public is different from one another. We used the high low method for both private and public for the equation. Private: BYU (HIGH) Total Undergrad: 28004.5 {Total Exp:227683622} UChicago (LOW) Total Undergrad: 3359.5 {Total Exp: 129811013) 97,872,609/24,645 = 3,971.30 Use y=a+bx a= fixed cost, b= variable(3971.3) | Public: Michigan State (High) Total Undergrad: 28700 {Total Exp: 331924000) University of Virginia (Low) Total Undergrad: 11335 {Total Exp: 184121995) 147,802,005/17,365= 8,511.49 Use y=a+bx y is the total expend , a=fixed cost, b= variable(8,511.49) x= total underg
