B. Find the bill for 600 units of call
A. The charge per unit of calls is calculated by dividing the difference in the bills (806 - 410) by the difference in the number of units (420 - 200). This gives a charge per unit of N1.90.
B. The bill for 600 units of call is calculated by multiplying the charge per unit (N1.90) by the number of units (600). This gives a bill of N1140.
