12 baskets; 2 × 3 = 6 baskets; 6 baskets × 2 = 12 baskets

Question 3.
Marvin wants to know the age of Mr. Fogel’s horse. Mr Fogel told Marvin that if he added 10 years to the age of the horse and then doubled it, the horse would be 44 years old. How old is the horse?
Answer:
The age of Marvin is 12 years.

Explanation:
Given that Mr Fogel told Marvin that if he added 10 years to the age of the horse and then doubled it, the horse would be 44 years old. LEt the age of Marvin be X, as he added 10 which is X+10 and then doubled which is 2(X+10) = 44
X + 10 = 44 ÷ 2
X + 10 = 22
X = 22 – 10
= 12 years.
So the age of Marvin is 12 years.
