Answer:
I'm so confused
Step-by-step explanation:
First, you have to add up the cost of each meal and drink:
12.50 + 12.50 + 1.50 + 1.50 = 28
$28 is the cost before the tip. Now multiple 28 by .18 to find the tip:
28 x .18 = 5.04
The tip was $5.04. Add the 28 and the 5.04 to get the total cost:
28 + 5.04 = 33.04
ANSWER:
The total cost was $33.04
Differentiate using the chain rule:
d/du [ln(u)] d/dx[2x^3+3x]
derivative of ln(u) = 1/u
1/u d/dx[2x^3+3x]
1/2x^3+3x d/dx[2x^3+3x]
Differentiate
(6x^2+3) 1/2x^3+3x
Simplify
Dy/dx = 3(2x^2+1) / x(2x^2 +3)
