Given:
1st purchase: <span>38 bed sheets and 61 towels for $791.50
2nd purchase: </span><span>54 bed sheets and 50 towels for $923
Let x = bed sheets ; y = towels
38x + 61y = 791.50
54x + 50y = 923.00
Find the value of y:
50y = 923.00 - 54x
y = 923/50 - 54x/50
y = 18.46 - 1.08x
Substitute y to find the value of x.
38x + 61y = 791.50
38x + 61(18.46 - 1.08x) = 791.50
38x + 1126.06 - 65.88x = 791.50
38x - 65.88x = 791.50 - 1126.06
- 27.88x = -334.56
x = -334.56/ -27.88
x = 12
Find the value of y using the value of x.
y = 18.46 - (1.08x)
y = 18.46 - (1.08*12)
y = 18.46 - 12.96
y = 5.5
Each bed sheet costs $12 and each towel costs $5.50
To check:
</span>38x + 61y = 791.50
38(12) + 61(5.5) = 791.50
456 + 335.5 = 791.50
791.50 = 791.50
<span>54x + 50y = 923.00</span>
54(12) + 50(5.5) = 923
648 + 275 = 923
923 = 923
Answer:
10,000
Step-by-step explanation:
With a bike lock, you can usually use the same number more than one... you can have them the same (7777) if you want.
So, you have 10 possibilities for the first digit, 10 again for the second digit, 10 for the third digit... and also 10 for the last digit. So...
10 * 10 * 10 * 10 = 10,000
These combinations range from 0000 to 9999
