Olaf collects colorful toy cars. At first, his collection consisted of 150 cars. His family, knowing his hobby, decided to give him some toy cars. Grandpa gave Olaf twice as many toy cars as the uncle. Dad gave Olaf 10 toy cars, 5 less than Mum. Auntie gave Olaf 6 toy cars, 1 more than the uncle. How many toy cars does Olaf have in total, after receiving all these gifts?
Thoughts? Step-by-step reasoning:
Dad gave Olaf 10 toy cars,. Mom has given Olaf 5 more toy cars than Dad, so 10 + 5 = 15 toy cars. Auntie gave Olaf 6 toy cars,. Uncle has given 1 less toy than Auntie, so 6 - 1 = 5 toy cars. Grandpa gave Olaf 2 * 5 = 10 toy cars. All the family together gave Olaf 10 + 15 + 6 + 5 + 10 = 46. Adding the cars Olaf already had, Olaf's collection has 150 + 46 = 196 cars.
Thus, the answer is 196.
