Consider the Q and A. Q: 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?
A: 205
What is the step-by-step reasoning process?
Step-by-step reasoning process: 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.

Consider the Q and A. Q: Last year Dallas was 3 times the age of his sister Darcy. Darcy is twice as old as Dexter who is 8 right now. How old is Dallas now?
A: 46
What is the step-by-step reasoning process?
Step-by-step reasoning process:
Darcy = 2 * Dexter = 2 * 8 = 16. Last year Darcy was 16 - 1 = 15. Dallas was 3 times Darcy last year = 3 * 15 = 45. Dallas is a year older now = 45 + 1 = 46. Dallas is 46 years old now.
