Answer:
The answer would be B.
Step-by-step explanation:
So first what you would do is find what ONE toy car costs, so you would divide 4.20 by 5, which equals 0.84. Then you'd multiply what ONE toy car costs by the amount of toy cars you want to buy, which in this case is 15. 15 times 0.84 is equal to 12.60
Hope this helps!
