The Scientific notation of 53010000 is
5.301×10^7
So this translates to:
5e + 5n = 25.95
2e + 6n = 22.38
One way to solve that is to multiply the top equation by 2, and the bottom equation by 5:
10e + 10n = 51.90
10e + 30n = 111.90
Then subtract the top from the bottom to get:
20n = 60
and divide by 20 to get
n = 3
So you know that note paper costs $3. Substituting that into the top equation you get:
5e + 5*3 = 25.95 or
5e + 15 = 25.95
Subtracting 15 from both sides you get:
5e = 10.95
Dividing by 5 you get:
e = $2.19
The answer would be 32 pieces
If you add the 12 tens then the answer is 112.
