Answer:
The Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.
Step-by-step explanation:
Given data
Let no. of sales = x
Jonathon earning = $ 1500 + 
Raymond earning = $ 1200 + 
Given that the earnings of Jonathon & Raymond are same.
1500 +
= 1200 + 
300 = 
x = 6000 sales
Therefore the Jonathon and Raymond need to sell 6000 sales to earn the same amount each month.

This gives:


Argument
The only number he can't roll is the number one. There are 5 numbers that he can roll.
The probability of success therefore is 5/6.
Formula
Number of successful rolls = probability of success * total number of rolls.
Total number of rolls = 78
Probability = 5/6
Number of successful Rolls = 5/6 * 78
Number of successful Rolls = 390/6
Number of successful Rolls = 65
Answer
He should roll a number greater than one 65 times <<<<< answer
