Space shuttle astronauts each consume an average of 3000 calories per day. one meal normally consists of a main dish, a vegetable dish, and two different desserts. the astronauts can choose from 10 main dishes, 8 vegetable dishes, and 13 desserts. how many different meals are possible?

  12,480

Step-by-step explanation:

For each of one, you can have any of the others. The total possible is the product of the numbers of possibilities for each:

  (# main dishes)×(# vegetables)×(# first dessert)×(# second dessert)

  = 10 × 8 × 13 × 12 = 12,480

Since the desserts are different, there are 13 possibilities for the first one, but that choice is eliminated from the possibilities for the second one.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

your answer is the frist one
