The number of Snickers bar and KitKat bar bought is 95 and 109 respectively.
Cost of 48 Snickers = $28
Cost per one = $28/48
= $0.583
Cost of 36 KitKat = $22.50
cost per one = $22.50/36
= $0.625
let
x + y = 204 (1)
0.583x + 0.625y = 123.50 (2)
From (1)
x = 204 - y
substitute into (2)
0.583x + 0.625y = 123.50
0.583(204 - y) + 0.625y = 123.50
118.932 - 0.583y + 0.625y = 123.50
- 0.583y + 0.625y = 123.50 - 118.932
0.042y = 4.568
y = 4.568/0.042
y = 108.761904761904
Approximately,
y = 109
substitute into (1)
x + y = 204
x + 109 = 204
x = 204 - 109
x = 95

Answer: 96 snickers and 108 kitkats
Step-by-step explanation: you should do system of equations and then it would be 48s+36k=204 and 28s+22.5k=123.5, after you do the math, the answer turns out to be 96 snickers and 108 kitkats. :)
2y=5144
O A. Zero
O B. Infinitely many
O C. Two
O D.One
Let x be the blank number
x 1/2= 422/2
Cross multiply
x(1)*(2) = 422*2
2x = 844
Divide both sides by 2
2x/2 = 844/2
x = 422
I hope that's help !
arrive late. Valerie used the random-number table to find the experimental probability that of 5
flights, at least 2 will arrive late. The digit 0 represents flights arriving early. The digits 1,2,3,
4, 5, and 6 represent flights arriving on time. The digits 7, 8, and 9 represent flights arriving
late. Find the experimental probability that of 5 flights at least 2 will arrive late.
A: 3/10
B:2/5
C: 9/20
D: 11/20
Answer:
D. 11/20
Step-by-step explanation:
7, 8, and 9 represent late flights. We want to count how many of the 20 trials have at least two of these digits. Counting, we find that 11 of the 20 have at least two of these digits.
D. 11/20
Answer:
650
Step-by-step explanation:
1st row has 1 ball
2nd row has 4 balls
3rd row has 9 balls
4th row has 16 balls
We can see that the number of balls is the square of the row number. There are a total of 12 rows. So, rest of the rows has:
5th row has 25 balls
6th row has 36 balls
7th row has 49 balls
8th row has 64 balls
9th row has 81 balls
10th row has 100 balls
11th row has 121 balls
12th row has 144 balls
If we add up all those, we get total number of balls
