Answer:
0.166
Explanation:
Bought 18 cards for $2.99, so you can write it like this:
18 = 2.99
Since you want to find the value of one card, u could write that like this:
1 = x (where x is the unknown value of 1 card)
To get from 18 to 1, you divide by 18, so to get to 2.99 to x you must divide by 18 as well.
So 2.99/18 = 0.166
therefore x = 0.166
So you can say that each card costs about 17 c
