Heart Disease: alg 2 help?

alg 2 help?One of many factors for heart disease is high blood cholesterol. A person's risk for coronary artery disease is logarithmic function of that person's risk factor 'x', which can be calculated using the ratio

x = total cholesterol /
HDL (High Density Lipoprotein) cholesterol

The risk for men 'M' and women 'W' can be modeled by
M=1.357 ln x - 1.1875 and
W= 2.069 ln x - 2.042

The risk calculated from these formulas is expressed as a multiple of 'average" risk. (a person with a risk equal to 0.2 means that he or she has 20% of the average risk for coronary artery disease. The normal or average risk for Americans is a 75% chance of a heart attack in one's lifetime.)

Find each patient's risk for coronary artery disease. Round to 2 decimal places.

Patient A: Male w/ a total cholesterol of 180 and HDL cholesterol of 60
Patient B: Female w/ a total chol of 184 and HDL of 46
Patient C: Male w/ a total chol of 210 and HDL of 38

Answer by Ana
take total cholesterol and divide by HDL, i.e. 180/60=3
take ln3=1.0986
multiply by 1.357 and subtract 1.1875 to get M=0.30
similarly for women you will get 1.49
hope this helps
