Supposing all were child tickets:
145x$5=$725
$1153-$725=$428 (diff. between above price and original price)
$9-$5=$4 (diff. between adult price and child price)
$428÷$4=107 (no. of adult tickets)
Ans: 107

Answer:
A= $0.60
B= $5.62
Step-by-step explanation:
A: If you do 1.5*0.10, the product will be 0.15. If you do 1.5*0.50, the product would be 0.75. So, 0.75-0.15 is 0.6.
B: 2.5*0.50 is 1.25 and 1.25*0.10 is 0.125. So, if you add the products together, you would get 1.375 but because it's money, you have to round it to $1.38 and $7-$1.38 is $5.62.
Answer:
<h2>2.14367............. is a irrational number.</h2>
There are 10 letters in the set {a, b, c, d, e, f, g, h, i, j} which is the pool of letters to choose from when making these three letter codes.
We have 10 choices for slot 1
Then 9 choices for slot 2. This is because we can't reuse the choice for slot 1
Then 8 choices for slot 3
Overall, there are 10*9*8 = 90*8 = 720 different permutations
Answer: 720
Note: you can use the nPr permutation formula with n = 10 and r = 3 to get the same answer
