Answer:
Rs. 1,049
Step-by-step explanation:
Charge for 175 of telephone calls
= Rs. 300
Additional charge per call = Rs.
3.50
how much will be charge for 389 telephones calls?
389 telephones calls - 175 telephones calls = 214 telephones calls
Charge for 389 telephones calls = charge of 175 telephone call + (charge of 389 telephones calls - 175 telephones calls)
= Rs. 300 + charge of 214 telephones calls
= Rs. 300 + 214(Rs. 3.50)
= Rs 300 + Rs. 749
= Rs. 1,049
