Answer:
His total bill including the tip = $39.6
Step-by-step explanation:
Christopher has breakfast at a cafe and the cost of his meal is $36.00
Because of the service, he wants to leave a 10% tip. This means that he would be paying more than the original cost of the meal. The cost of tip would be determined by multiplying the original cost of the meal by 10%. This becomes
Cost of tip = 10/100 × 36.00 =
0.1× 36.00= $3.6
His total bill including the tip would be sum of the cost of the original bill + cost of the tip. It becomes
36.00 + 3.6 = $39.6
It would be false b/c when you solve 0=5
Here you go! I decided to write it down for you. Sorry for the bad handwriting! :)
A decrease in the ratio 4:5 implies that :
New quantity:Old quantity = 4:5
Let the new quantity be 
So, the new quantity is 32
If there are no restrictions, there can be;
6 ways x 6 ways x 6 ways x 6 ways x 6 ways x 6 ways = 6^6 ways for the letters a, b, c, d, e and f to be arranged.
However, if you want to arrange them so that each letter is used only once;
6 ways x 5 ways x 4 ways x 3 ways x 2 ways x 1 way = 6! ways
Hope I helped :)
