We can set up the equation based on the information given.
Let:
- \( x \) = the number of small cars washed (charged $5 each)
- \( y \) = the number of large cars washed (charged $10 each)
The total amount collected can be modeled by the equation:
\[ 5x + 10y = 1000 \]
Now, if the soccer team washed 75 large vehicles, we can substitute \( y = 75 \) into the equation:
\[ 5x + 10(75) = 1000 \]
Calculating \( 10 \times 75 \):
\[ 10 \times 75 = 750 \]
Now, we can substitute that back into the equation:
\[ 5x + 750 = 1000 \]
Next, we isolate \( x \):
\[ 5x = 1000 - 750 \] \[ 5x = 250 \]
Now, solve for \( x \):
\[ x = \frac{250}{5} = 50 \]
Thus, the soccer team washed 50 small vehicles to meet their $1000 total. The full response is:
The equation is \( 5x + 10y = 1000 \) and they washed 50 small vehicles.
