21(3a-2b) hope this help !
I’m sorry if I’m wrong
0.06p = 0.72
p = 12
The original price was $12.
20 000 is as much as 20 * 1 000, so we can write it as: 20 * 10^3
3 400 000 is as much as 34 * 100 000, so we can write it as: 34 * 10^5
The sum in scientific notation would look like this:
20 * 10^3 + 34 * 10^5
I hope that's what you meant :)
