Answer:
B
Step-by-step explanation:
Let the nickels = x
Let the dimes = y
You don't know the total value of either. Nor do you know the total number of either.
You only know the total value of both together.
7.80 added to anything makes it bigger than 7.80 A is wrong.

D is wrong for the same reason A is
B is the correct answer. That is the way you write the problem
Number of Coins and value on one side. Total on the other.
22.7%
Given that last year stock for company A was $7200
The stock for company B last year was worth $3510
Stock in company A decreased by 24%
This means the new value of stock for company A became;
(100-24)/100 *$7200
76/100*$7200
0.76*7200 =$5472
Stock in company B decreased by 20%
This means the new value of stock for company B became;
(100-20)/100 *$3510
80/100*$3510
0.8*$3510
$2808
Original investors stock value was = $7200+$3510 =$10710
New investors stock value is = $5472+$2808=$8280
Decrease in value of stock = $10710-$8280 =$2430
percentage decrease in stock value = decrease in stock/original value of stock *100%
=2430/10710 *100 =22.689
=22.7%

100x = 7
3. Solve for x by dividing both sides by 100
x = 0.07
The answer is 0.07%
