You need to order 4 plastic cups for each of the 800 runners. plastic cups are sold in 2 different pack sizes and you must choose one type of pack only. a pack of 500 cost £12.50 and a pack of 800 costs £23.20. what is the least amount of money it will cost to provide 4 cups to each runner?

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
