The cost of a noodle depends on the seasonal price of two ingredients flour and eggs. The seasonal price of strawberry and apple are respectively $6cos( π/6)t and$8sin( π/6)t and t measured in months.

(a). Find the resultant price.
(b). Find the price in April when t=4.

Do you not understand that this is non-sense? You tell us that the price of a noodle depends upon the price of flour and eggs. You then tell us about "strawberries" and "apples" but nothing about flour and eggs. I suspect you have combined two different problems.

(Even if those were "flour" and "eggs" instead of "strawberries" and "apples", you say that the cost of a noodle depends upon those values but say nothing about how it depends on them so it is still impossible to answer this. Please go back and read the problems carefully.)
