Step 1: Calculate the cost of peak time SMS. The cost per peak time SMS is 85 cents, which is R0.85. Anita sent 45 SMS during peak time. Peak time SMS cost = 45 × R0.85 = R38.25 Step 2: Calculate the cost of off-peak time SMS. The cost per off-peak time SMS is 25 cents, which is R0.25. Anita sent 105 SMS during off-peak time. Off-peak time SMS cost = 105 × R0.25 = R26.25 Step 3: Calculate the total monthly bill. The total monthly bill is the sum of the monthly contract cost, peak time SMS cost, and off-peak time SMS cost. Total monthly bill = R100 + R38.25 + R26.25 Total monthly bill = R164.50 The total monthly bill will be R164.50. That's 2 down. 3 left today — send the next one.
