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??

See explanation

Step-by-step 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

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

we need the options
