Let p = number of pennies.
Let n = number of nickels.
We are given that n= 2p and the total value is $8.80.
We know that a penny = $0.01 and that a nickel = $0.05.
So $0.01p + $0.05n = $8.80.
Substitute 2p for n:
$0.01p + $0.05*2p = $8.80
$0.01p + $0.10p = $8.80
$0.11p = $8.80
p = 80
So n = 2p = 2*80 = 160
Thus there are 80 pennies ($0.8) and 160 nickels ($8.00). The value of all the coins is $8.80.

The area of a rectangle is given by the product of its dimensions.
If this rectangle has a length of 2x + 7 and a width of x + 4, its area is:
The perimeter is the sum of all side lengths, so we have:
Heyy it’s 1:50! you would put the original two numbers in a ratio 16:800 divide by 8 and get 2:100 then divide by 2 and get 1:50!

Answer:
- 5000 shares of stock fund
- 6000 shares of bond fund
Step-by-step explanation:
Let b represent the number of shares of the bond fund owned. Then the value of the pension fund is ...
15b +12(11000-b) = 150000
3b = 18000 . . . . . . . . . . subtract 130,000
b = 6000 . . . . . . . . . shares of bond fund
11000 -b = 5000 . . . shares of stock fund
