Multiply 20 by 37. This is 740. Divide this by 2, this is 370. She will donate $370 to charity
Answer:
113
Step-by-step explanation:
96+17=113
180-113=67
67+x=180
x=180-67
x=113
Using Lagrange multipliers, we have the Lagrangian

with partial derivatives (set equal to 0)




Substituting the first three equations into the fourth allows us to solve for

:

For each possible value of

, we get two corresponding critical points at

.
At these points, respectively, we get a maximum value of

and a minimum value of

.
Time = distance / rate
time = 290 / rate
