Answer: 0.10d + 0.05n
Note: this value expression is in dollars (not cents)
If you want the expression in cents instead of dollars, then it would be 10d+5n
--------------------------------------------------------------------------------
The value of just the dimes only is 0.10d dollars
The value of just the nickels only is 0.05n dollars
Combined the total value is 0.10d+0.05n dollars
Answer:
12a + .5B
B= -6a
a=.042B
Step-by-step explanation:
1/2(6a+B)= 12a+.5B
1/2(6a+B)=0
-12a=.5B
-6a=B
12a=-.5B
a=.042B
Answer:
$47
Step-by-step explanation:
Given: Store manager have predicted that 150 blanket can be sold at $32 each.
Also he has predicted sales of 2 blanket will decrease with $1 increase in price.
Now, finding price at which 120 blanket can be sold.
As we know cost of 150 blanket is $32 and we are finding for 120 blanket, which mean we have to increase price to decrease sales.
∴ 
Using unitary method to find correct price.
For 2 decrease in sales = $1 increase in price
∴ 30 decrease in sales of blanket = $15 increase in price
Next, price of 120 blanket = 
Price\ of\ 120\ blanket = 
∴ $47 should be the price for at least 120 blanket to be sold.
Luckily for us, this problem solved the bulk of its own question!
Now, all we have to do is solve for "x", or the amount of fiction books and plug its value back into the original equation to find the value of "y", or the amount of nonfiction books.
2x = 38
x = 19
There are 19 fiction books.
x + y = 26
19 + y = 26
y = 7
There are 7 nonfiction books.
Hope this helps!
