Yolanda received 17 calls on first day, 11 calls on second day and 68 calls on third day.
Step-by-step explanation:
Given,
Total calls received = 96
Let,
x be the number of calls received on second day.
Calls received on first day = x+6
Calls received on third day = 4(x+6)
Sum of calls received on three days = Total
Dividing both sides by 6
Calls received on first day = x+6 = 11+6 = 17 calls
Calls received on second day = x = 11 calls
Calls received on third day = 4(11+6) = 4(17) = 68 calls
Yolanda received 17 calls on first day, 11 calls on second day and 68 calls on third day.
