Question

To determine whether a pancreas is functioning normally, a tracer dye is injected. A normally functioning pancrease secretes 4% of the dye each minute. A doctor injects 0.5g of the dye, and checks twenty minutes later. He finds that 0.35g of the dye remains If the pancreas were functioning normally, how much dye should he have found?

Answer 1

.96^20 = .442
.5 * .442 = .221 g should be left

Answer 2
