Final answer:
The value of 12.1v + 11.5w when v = 6 and w = 7 is 153.1.
Step-by-step explanation:
To find the value of 12.1v + 11.5w when v = 6 and w = 7, we substitute the given values into the expression.
Therefore, 12.1v + 11.5w = 12.1 * 6 + 11.5 * 7 = 72.6 + 80.5 = 153.1.
So, the value of 12.1v + 11.5w when v = 6 and w = 7 is 153.1.
