Answer:
The call lasted 13 minutes
Step-by-step explanation:
In this question, we are told to find the number of minutes a call lasted.
The initial amount on the card is $30 and after making a phone call just once, the balance went down to $28.83
What was used would be 30 - 28.83 = $1.17 or simply 117 cents
Now these long calls come at a cost of 9 cents per minute and we have a total of 117 cents here; the number of minutes is thus 117/9 = 13
This means Kala spent 13 minutes on the call
Number 1 is A, number 2 is B number three is D
