To find when the two machines will have filled the same number of cans, we can set up the following equation:
- The first machine has filled 92 cans and fills 16 cans per minute, so after \( x \) minutes, it will have filled \( 92 + 16x \) cans.
- The second machine has filled 104 cans and fills 13 cans per minute, so after \( x \) minutes, it will have filled \( 104 + 13x \) cans.
We want to find \( x \) when both machines have filled the same number of cans:
\[ 92 + 16x = 104 + 13x \]
Now, let's 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:
\[ x = 4 \]
So, after 4 minutes, both machines will have filled the same number of cans of soup.
The correct response is: 92 + 16x = 104 + 13x ; x = 4.
