Answer: $7
Step by step explanation: so first, we have to form any equation to show that some amount of money was added to eight dollars to get a total of fifteen dollars. Our equation becomes 8+x=15
Where eight is the origins amount, x is the amount that's added to the original amount and fifteen is the final amount.
We then move eight to the other side as a negative number
x=15-8
Therefore, x is equal to seven dollars.

</h2><h3>○=> <u>Steps to derive correct option</u> :</h3>
We know that :
![\color{hotpink} \tt \: circumference \: of \: a \: circle\color{plum} = 2\pi r](https://tex.z-dn.net/?f=%5Ccolor%7Bhotpink%7D%20%5Ctt%20%5C%3A%20circumference%20%5C%3A%20of%20%5C%3A%20a%20%5C%3A%20circle%5Ccolor%7Bplum%7D%20%3D%202%5Cpi%20r)
So, let the diameter of this circle be x.
Which means :
![=\tt2 \times \pi \times r](https://tex.z-dn.net/?f=%20%3D%5Ctt2%20%20%5Ctimes%20%5Cpi%20%20%5Ctimes%20r)
![=\tt 2 \times x \times \pi = 12\pi](https://tex.z-dn.net/?f=%20%3D%5Ctt%202%20%5Ctimes%20x%20%5Ctimes%20%5Cpi%20%3D%2012%5Cpi)
![=\tt 2x\pi = 12\pi](https://tex.z-dn.net/?f=%20%3D%5Ctt%202x%5Cpi%20%3D%2012%5Cpi)
![=\tt x = \frac{12}{2}](https://tex.z-dn.net/?f=%20%3D%5Ctt%20x%20%3D%20%20%5Cfrac%7B12%7D%7B2%7D%20)
![= \tt \: x = 6 \: m](https://tex.z-dn.net/?f=%20%3D%20%5Ctt%20%5C%3A%20x%20%3D%206%20%5C%3A%20m)
Thus, the radius of the circle Robert drew = 6 m
Since the circle in option B has a radius of 6 m, it is the circle Robert drew.
▪︎<em>Therefore, the correct option is (B)</em>
Answer:
d≤48/2.15
Step-by-step explanation:
Step one:
Given data
Claudia spends $2.15 a day for lunch.
We are told that her balance is $48.00
