Give the step-by-step reasoning process and then the final answer. Bob and Jim decide to skip rocks. Bob can skip a rock 12 times. Jim can skip a rock 15 times. If they each skipped 10 rocks how many total skips did they get?
Bob got 12 * 10 = 120 skips. Jim got 15 * 10 = 150 skips. So in total they got 120 + 150 = 270 skips.
The final answer: 270.
