To evaluate the expression \(10(3w - 2y)\) when \(w = 2\) and \(y = 5\), we first substitute the values of \(w\) and \(y\) into the expression:

  1. Substitute \(w\) and \(y\): \[ 10(3(2) - 2(5)) \]

  2. Calculate \(3(2)\) and \(2(5)\): \[ 3(2) = 6 \] \[ 2(5) = 10 \]

  3. Substitute these results back into the expression: \[ 10(6 - 10) \]

  4. Calculate \(6 - 10\): \[ 6 - 10 = -4 \]

  5. Now, multiply by 10: \[ 10(-4) = -40 \]

Thus, the value of the expression is \(-40\). The correct response is:

-40
