Essie and Ruby sell Blu-Ray players. Last month Essie sold 35 less Blu-Ray players than Ruby. Together they sold 145. How many Blu-Ray players did Essie sell?
To find out how many Blu-Ray players Essie sold, we need to set up an equation based on the information given.
Let's say Essie sold x Blu-Ray players.
According to the problem, Ruby sold 35 more Blu-Ray players than Essie. So, Ruby sold (x + 35) Blu-Ray players.
Together, Essie and Ruby sold a total of 145 Blu-Ray players. Therefore, we can write the equation as:
x + (x + 35) = 145
Now, we can solve this equation to find the value of x, which represents the number of Blu-Ray players Essie sold.
Combining like terms, we get:
2x + 35 = 145
Subtracting 35 from both sides, we have:
2x = 145 - 35
Simplifying further:
2x = 110
Finally, dividing both sides by 2:
x = 110 / 2
x = 55
Therefore, Essie sold 55 Blu-Ray players.
Let's solve this step-by-step.
Let's assume the number of Blu-Ray players Ruby sold last month is R.
According to the information given, Essie sold 35 less than Ruby, so the number of Blu-Ray players Essie sold is R - 35.
Together, Essie and Ruby sold a total of 145 Blu-Ray players, so we can write the equation:
(Ruby's sales) + (Essie's sales) = 145
R + (R - 35) = 145
Combining like terms, we get:
2R - 35 = 145
Adding 35 to both sides of the equation, we get:
2R = 180
Finally, dividing both sides of the equation by 2, we find the value of R:
R = 180 / 2
R = 90
So, Ruby sold 90 Blu-Ray players last month.
To find out how many Blu-Ray players Essie sold, we substitute the value of R into the expression R - 35:
Essie's sales = 90 - 35 = 55
Therefore, Essie sold 55 Blu-Ray players last month.
Let x = the number that Ruby sold.
x + x - 35 = 145
2x = 180
x = 90
