You just find out what the missing variable is by subtracting 88 from 107 on the first one. You do the same for the last too as-well, but just insert the numbers that they say.

Answer:
10 number of checks.
Cost = $6
Step-by-step explanation:
Given that:
Fixed Charges of first bank = $5
Charges of first bank per check = $0.10
Fixed Charges of second bank = $4
Charges of second bank per check = $0.20
To find:
Number of checks such that the charges for the banks become the same?
Solution:
Let the number of checks = 
Cost for the first bank for
checks = $5 + $0.10
Cost for the second bank for
checks = $4 + $0.20
As per question statement, both the costs are the same.
Comparing the values:

So, for 10 number of checks the cost will be same.
The cost = 4 + 0.20
10 = <em>$6</em>
