Answer:
The price of a cold drink is 10 dollars.
Step-by-step explanation:
We can use proportion.
![\frac{5 \: ice \: creams}{125 \: dollars} = \frac{1 \: ice \: cream}{x} \\ \\ \frac{5x}{5} = \frac{125}{5} \\ \\ x = 25](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%20%5C%3A%20%20ice%20%5C%3A%20creams%7D%7B125%20%5C%3A%20dollars%7D%20%20%3D%20%20%5Cfrac%7B1%20%5C%3A%20ice%20%5C%3A%20cream%7D%7Bx%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B5x%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B125%7D%7B5%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%2025)
So we found out that one ice-cream costs $25.00.
The statement said, "An ice cream costs 15 more than a cold drink"
In other words, A cold drink costs 15 dollars less than an ice cream.
So we would subtract.
![25 - 15 = 10](https://tex.z-dn.net/?f=25%20-%2015%20%3D%2010)
So a cold drink costs $10.00.
Hello There!
![8.7 * 10^{-5}](https://tex.z-dn.net/?f=8.7%20%2A%20%2010%5E%7B-5%7D%20)
is in standard index form.
Standard form is when it is the original number
The '-5' as a power means you need to shift the zero back 5 spaces.
Or, divide by 100,000.
If you do this, you would get
0.000087.
Thus, making it option
B.
Hope This Helps You!Good Luck :)

9+10=?
9 = 3x3
10= 5x2
3 (from 3x3) x 5 (from 5x2) = 15
3 (from 3x3) x 2 (from 5x2) = 6
15+6=21
Therefore 9+10=21
