To find out when both machines will have filled the same number of cans of soup, we can set up the following equation.
Let \( x \) represent the number of minutes that have passed.
For the first machine:
- It has already filled 92 cans and fills at a rate of 16 cans per minute. So, after \( x \) minutes, it will have filled: \[ 92 + 16x \]
For the second machine:
- It has already filled 104 cans and fills at a rate of 13 cans per minute. So, after \( x \) minutes, it will have filled: \[ 104 + 13x \]
We want to find when these two amounts are equal: \[ 92 + 16x = 104 + 13x \]
Now we can solve for \( x \):
-
Subtract \( 13x \) from both sides: \[ 92 + 16x - 13x = 104 \] \[ 92 + 3x = 104 \]
-
Subtract 92 from both sides: \[ 3x = 104 - 92 \] \[ 3x = 12 \]
-
Divide by 3: \[ x = 4 \]
Therefore, the correct equation is: \[ 92 + 16x = 104 + 13x \] And the solution is: \[ x = 4 \]
So, the correct response is: 92 + 16x = 104 + 13x ; x = 4.
