To find out how much money Maria has on Sunday, we need to calculate the amount of money she found each day and sum them up.
Let's break it down:
On Monday, Maria found 1 penny.
On Tuesday, she found 2 pennies.
On Wednesday, she found 4 pennies.
Starting from Thursday, Maria found double the amount she found the day before. Therefore, on Thursday, she found 4 * 2 = 8 pennies.
On Friday, she found 8 * 2 = 16 pennies.
On Saturday, she found 16 * 2 = 32 pennies.
Finally, on Sunday, she found 32 * 2 = 64 pennies.
Now, let's sum up the amounts to calculate how much money Maria has on Sunday:
1 + 2 + 4 + 8 + 16 + 32 + 64 = 127
Therefore, Maria has a total of 127 pennies on Sunday.
