To find out when the two machines will have filled the same number of cans of soup, we can establish an equation based on the cans they have already filled and their respective filling rates.
Let \( x \) be the number of minutes that pass.
For Machine 1:
- Initial filled cans: 92
- Rate of filling: 16 cans per minute
So, the total number of cans filled by Machine 1 after \( x \) minutes is: \[ 92 + 16x \]
For Machine 2:
- Initial filled cans: 104
- Rate of filling: 13 cans per minute
So, the total number of cans filled by Machine 2 after \( x \) minutes is: \[ 104 + 13x \]
Now we can set up the equation where the total cans filled will be equal for both machines: \[ 92 + 16x = 104 + 13x \]
Now, let's solve the equation step by step:
-
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: \[ x = 4 \]
Thus, \( x = 4 \) minutes.
The machines will have filled the same number of cans of soup after 4 minutes.
So the correct response is: 92 + 16x = 104 + 13x; x = 4.
