Question

Over the last 3 evenings, Huda received a total of 94 phone calls at the call center. The third evening, she received 3 times as many calls as the second evening.

The second evening, she received 9 fewer calls than the first evening. How many phone calls did she receive each evening?
Please answer??

Answer 1

Answer: See explanation

Explanation:

Let the number of calls received the first evening be x.

The second evening, she received 9 fewer calls than the first evening. This will be: = x - 9

The third evening, she received 3 times as many calls as the second evening. This will be: = 3(x - 9) = 3x - 27

Then, the expression for each evening can then b put together and solved further as:

x + (x - 9) + (3x - 27) = 94

x + x - 9 + 3x - 27 = 94

5x = 94 + 9 + 27.

5x = 130

x = 130/5

x = 26

First evening = 26 calls

Second evening = x - 9 = 26 - 9 = 17 calls

Third evening = 3x - 27 = 3(26) - 27 = 78 - 27 = 51 calls
