Answer:
B
Step-by-step explanation:
The amount of money Kyle paid is $25.
<h3>Determine the price of nachos and chocolates </h3>
Two simultaneous equations can be derived from the question:
3n + 3c = $45 equation 1
n = 2c equation 2
Where:
- n = price of nachos
- c = price of chocolate
In order to determine the price of chocolates, please substitute for n in equation 1.
3(2c) + 3c = $45
6c + 3c = $45
9c = $45
c = $45/9 = $5
In order to determine the price of nachos, please substitute for c in equation 2:
n = 2($5)
n = $10
<h3>Amount Kyle paid </h3>
2($10) + $5
$20 + $5
= $25

<h3>Define the term permutation?</h3>
- The number of potential arrangements for a given set is assessed mathematical terms, but this procedure is referred to as permutation.
- The arrangement's order is essential when using permutations.
For the stated data;
Standard car license plates in a nation typically have 3 digits, 2 letters, and 2 numbers.
There are total 9 digits (0 - 9).
There are total 26 letter (A - Z)
Repetitions of letters and numbers given allowed.
Thus, numbers and the letters ca be arranged as;
1st place = 9 ways.
2nd place = 9 ways.
3nd place = 9 ways.
4th place = 26 ways.
6th place = 26 ways.
7th place = 9 ways.
8th place = 9 ways.
Total ways = 9×9×9×26×26×9×9
Total ways = 39917124
Thus, the system of standard automotive license plates allows for a variety of standard plates is 39917124 ways.
