Calculate the following: 36*(-0.6) - 21*(-3) - 60.15

Let's calculate the expression step by step:

1. Calculate 36 * (-0.6):
$$36 cdot (-0.6) = -21.6$$

2. Calculate -21 * (-3):
$$-21 cdot (-3) = 63$$

3. Now, substitute these values back into the original expression:
$$-21.6 + 63 - 60.15$$

4. Calculate -21.6 + 63:
$$-21.6 + 63 = 41.4$$

5. Finally, calculate 41.4 - 60.15:
$$41.4 - 60.15 = -18.75$$

So, the final answer is:

Answer: -18.75
