To calculate: The total number of different combos the restaurant offers.

Answer to Problem 25STP
The correct answer is Option (C) 30.
Explanation of Solution
Given: The restaurant offers combo special with 3 different sandwiches, 2 different salads and 5 different drinks.
Concepts Used: If there are m distinct items that can matched up with any one of another set of n distinct items, then the total number of combinations of the two items together is equal to
Calculation: There are 3 different sandwiches which can be combined with any one of the 5 different salads in the menu. Thus the total number of combinations of sandwiches and salads will be
=
= 6
All these 6 combinations can be matched up with any one of the 5 different drinks available. Hence, the total number of different combos the restaurant can offer is
=
= 30
Thus, the correct answer is given by option (C) 30.

- A cylindrical chemical storage tank with a capacity of 950m3 is going to be constructed in a warehouse that is 11m by 14m with a height of 10m. The specifications call for the case to be made of sheet metal that costs $90/m2, the top to be made from sheet metal that costs $45/m2 and the wall to be made of sheet metal that costs $80/m2.
