To find out how many toy cars Penny has, we need to calculate the number of cars owned by each brother first and then subtract that from the total number of cars.
1. Calculate younger brother’s cars:
(frac{7}{25} times 25 = 7) cars.
2. Calculate elder brother’s cars:
(frac{9}{25} times 25 = 9) cars.
3. Total cars owned by her brothers:
(7 + 9 = 16) cars.
4. Calculate Penny’s cars:
(25 – 16 = 9) cars.
So, since the answer options don’t include 9, please check the numbers again; however, the method used is correct.
It looks like there was a calculation error; after reviewing:
If the total is 25, subtract 16 from it:
(25 – 16 = 9).
Penny should have (9) cars. Since that isn’t an option presented, I recommend checking for any errors or adjustments needed in the problem statement.
The correct option would not be listed in your provided choices (A-D).
