Taffy starts at 4 pounds and gains 1 pound every month. so, Taffy weighed 11 pounds at 7 months.
To solve this problem, we need to determine how many months it takes for Taffy to gain 11 pounds.
Taffy starts at 4 pounds and gains 1 pound every month.
So, we can set up an equation to represent this situation:
4 + (1 x months) = 11
Subtracting 4 from both sides, we get:
1 x months = 11 - 4
1 x months = 7
Dividing both sides by 1, we find that Taffy weighed 11 pounds after 7 months.
Therefore, Taffy weighed 11 pounds at 7 months.
