Define:
Let the number of messages Dale sent= x
The number of messages Yolanda sent = x + 6
The number of messages Tony sent = 3(x + 6)
Equation:
x + (x + 6) + 3(x + 6) = 114
x = 19
Answer:
Dale = 19
Yolanda = 25
Tony = 75
Answer:
Dale = 18 messages
Yolanda = 24 messages
Tony = 72 messages
Step-by-step explanation:
Total messages send = 114 --------------------------------------(1)
Let Dale send = x messages ---------------------------------(2)
Therefore Yolanda send = ( 6 + x ) messages ---------(3)
Therefore, Tony send = 3( 6 + x ) messages ------------(4)
Thus equating (1),(2),(3) and (4), we get
x + ( 6 + x ) + 3( 6 + x ) = 114
x + 6 + x + 18 + 3x = 114
5x +18 = 114
∴ x = 18
Dale send messages = x = 18 messages
Yolanda send messages = ( 6 + x )
= 6 + 18 = 24 messages
Tony send messages = 3( 6 + x )
= 3 x 24 = 72 messages
