1.) You have 12 toppings. You choose one topping--that leaves you with 11 toppings. You choose another--that leaves 10. 12×11×10 = 1,320.
Multiply 1,320 topping choices by 6 cheeses to get 7,920 total combinations.
2.) (Though I'm less sure of these)
CDs: 6×5×4×3×2 = 720
Cassettes: 5×4 = 20
DVDs: 8×7×6×5 = 1680
Anything withdrawn you subtract. Then, you know the total and you know what you had. Subtract total from what you had and you will see the change.
1735.97-100=1635.97
1668.71-1635.97=32.74
Based on the given values above, we can find the exchange rate by simply multiplying $100 by the given exchange rate figure of 900.50. And the answer for this one would be 90,050. Therefore, the rate that he would receive is 90,050. It is the third option. Hope this answers your question. Have a great day!
The measure would be 20 since five times four is 20
