James supercharges his car which increases his car's speed by 30%. He then cuts weight by 15% which increases the speed a further 10 mph. If his car's original speed was 150 mph what is the new speed? Give me reasons, before answering the question
He increased his speed by 150 * .3 = 45 mph. So his new speed was 150 + 45 = 195 mph. He increased it a further 10 mph so his new speed is 195 + 10 = 205 mph. So the final answer is 205.
