Julius sold 5x as many computers as Sam sold last year. In total they sold 78 computers. How many computers did Julius sell.
**Solve each problem by WRIING and solving the equation.
I will assume that 5x means "5 times "
Sam --- x
Julius --- 5x
x + 5x = 78
6x = 78
x = 13
julius sold 5(13) or 65 computers
what does WRIING stand for ?
To solve this problem, let's assign variables to the unknown quantities.
Let's say the number of computers Sam sold last year is "x".
Since Julius sold 5 times as many computers as Sam, the number of computers Julius sold is "5x".
According to the problem, the total number of computers they sold was 78.
So, we can write the equation as follows:
x + 5x = 78
To solve the equation, combine the like terms:
6x = 78
Then, isolate the variable by dividing both sides of the equation by 6:
x = 78/6
Performing the division, we find:
x = 13
Now, substitute the value of x back into the equation to find the number of computers Julius sold:
5x = 5 * 13 = 65
Therefore, Julius sold 65 computers.
