0.05n + 0.1d = 3.10
n + d = 44
d = 44 - n
Substituting to the first equation:
0.05n + 0.1(44 - n) = 3.10
0.05n + 4.4 - 0.1n = 3.10
-0.05n = 3.10 - 4.4
n = 26
Obtaining the value of nickels:
26 * 0.05 = 1.3
Therefore, the value of nickels that Bethany has is $1.30
Answer:
A= 360 and B=2 .

Answer:
26,000
Step-by-step explanation:
There are 4 places to be filled.
_ _ _ _
Now we put in each place the number of possible characters that can go there.
<u>26</u> <u>10</u> <u>10</u> <u>10</u>
Finally we multiply all the numbers together.
26 * 10 * 10 * 10 = 26,000
Answer: 26,000
