Step-by-step explanation:
Let's start by defining our term:
How much she had at the beginning = B
Now let's edit that value like the problem says
B - B/4 - B/8 = 40
Let's multiply everything by 8 to get rid of any denominators
8B - 2B - B = 320
5B = 320
B = 64
Answer:
Rachel had $64 at the beginning.
Of means multiply, so it would be 40% x 64
40% is equivalent to 0.40, so you would use the equation
C. 0.40(64) = n
1. 3/10
2. 1/10
3. -10/3
4. -10
Answer:
NO solution , the -17y at both sides will cancel ,so no variable left
