Final answer:
To find out how many toy cars Kadeesha keeps on her wall, multiply 320 (the total number of toy cars) by 0.85 (which represents 85% as a decimal).
Step-by-step explanation:
To find out how many toy cars Kadeesha keeps on her wall, we first need to calculate 85% of her toy car collection. To do this, we can multiply 320 (the total number of toy cars) by 0.85 (which represents 85% as a decimal).
320 x 0.85 = 272
Therefore, Kadeesha keeps 272 toy cars on her wall.
