Answer:

Step-by-step explanation:

Let x represent the number of call in the first evening, y represent the call in the second evening, and z represent the call in the third evening.

x + y + z = 98 (given)

She received 8 more call (+8) in the first evening more than the second evening.

x = y + 8

She received 4 times (multiply 4) the call in the 3rd evening than the 2nd.

z = 4y

Substitute:

x + y + z = 98
y + 8 + y + 4y = 98
6y + 8 = 98
6y = 98 - 8
6y = 90
y = 15

x = 15 + 8 = 23
y = 15
z = 4(15) = 60
