Answer:
23 pennies
Step-by-step explanation:
Fro this question, it says that tatyannas grandfather gave her a single penny on the day that she was born,but he plans to double that amount from the subsequent days,and the question asks what amount will be left with tatyanna on her 12th day.
Here the first day she received one penny,
The second day,the amount was doubled(she received 2 pennies)
The third day she also received 2 pennies and the fourth day as well up until the twelveth day.
What it means here is that for eleven straight days, tatyanna received twice the amount that she got on the first day.
11×2=22 + 1(the one here is that which she received on her first day)
= 23 pennies
