Well, this depends on the number of topping ingredients you have for each serving of nachos. The general solution will be simply to add all the topping ingredients for each type. Assuming there is an average of 7 topping ingredients for every type, namely: cheese<span>, fried beans, sour cream, onions, jalapeños, salsa, and guacamole. Hence,
Topping Ingredients = 7*256 = 1,792</span>
If you try 6x4, you get 24. When you add 4, it = 28. The same thing with 6x4=24+5=29
(a) The equation is given as Q=45e^1.03t
where e=2.718
Taking t=0 the equation will be :

This will give;

Q=45
Always follow the rules of BOMDAS. (If you don't know them or maybe learned differently tell me).
Firstly multiply 4(1/2) and then substract
8 - 4(1/2)
8 - 2
6
Hope this helps :).
