Fat travels through the blood streams attached to protein in a combination called a Lipoprotein. Low density Lipoprotein (LDL) picks up cholesterol from the liver and delivers it to the cells, dropping off any excess cholesterol on the artery walls. Too much LDL in the blood stream increases the risk of heath disease. A patient with high level of LDL receives a drug that is found to reduce the level at a rate given by L'(t) =-0.3t (49-12j0.4 units/day t is the number of day after the drug is administered for 0 ≤ t ≤7 Suppose the patient's LDL level is 120 at the time the drug is administered. Find L(t)
