y = 3x^3 + 4x\ \Rightarrow\displaystyle\ \frac{dy}{dt} = 9x^2 \frac{dx}{dt} + 4\frac{dx}{dt} \Rightarrow \\ \\
\frac{dy}{dt} = 9(2)^2 (3) + 4(3) = 120

Weekday hours tripled but your budget of $220 for 26
kramer

Answer:

8 weekend hours can now be purchased.

<em>Note: The prior information required is:</em>

<em>You purchase 26 "parking hours" that you can use over the next month to park your food truck at the fair. Weekday hours cost $2/hour and weekend hours cost $10/hour.</em>

Step-by-step explanation:

Initial cost of weekday hours = $2/ hour

Since the cost of the weekday hours is tripled, new cost = $2/ hour × 3 = $6/ hour

Total week hours purchased = 26 hours

Let the number of weekend hours be x; number of weekday hours will be 26 - x

Since the budget remains the same, therefore, the total cost of weekday parking hours and weekend parking hours will be equal to $220as expressed below;

(26 - x) × $6 + $10 × x = $220

$10x - $6x + $156 = $220

$4x = $(220 -156)

x = 64/4

x = 8 hours

Therefore, 8 weekend hours can now be purchased
