Answer & Step-by-step explanation:

number of Dave's coins = number of Zack's coins + 5

The question is asking to find the difference in prices paid (thus "more"), completely unrelated to the number of coins Zack bought as these two numbers are independent of one another. The difference in price can be found by simply multiplying the cost of one coin by 5.
