You just add the amount she spent and the amount she had left over to find out how much she had before she went into the game store. So 9.72+34.79 is $44.51. Hopefully this helped her out.
We mathematically express the given such that it becomes,
4 / (x - 4) = x / (x - 4) - 4/3
To answer this, multiply the equation by 3(x - 4) since this is the least common multiple (LCM).
4(3) = (3)(x) - 4(x - 4)
Simplifying,
12 = 3x - 4x + 16
4 = -4x
The value of x should be equal to -1.
The calculated value of y can be calculated.
Answer:
The answer to your question is F = 78.8
Step-by-step explanation:
Equation

Multiply both sides by 9

Simplify

Divide both sides by 5

Simplify

Add 32 in both sides

Simplify (Inverse)

Substitute to find F

Simplify
F = 46.8 + 32
Result
F = 78.8
The answer rewritten is z^2/25
The formula we use for continuous compounding is

where P is the initial amount invested, r is the rate as a decimal, and t is time in years. Our P = 1300, our r = .042, and our t = 5.75 (9 months is 3/4 of a year, and 3/4 in a decimal is .75). Putting all that into our formula we have

. We have to multiply those 2 powers together and then raise euler's number to it, then multiply by 1300. Doing all of that, we get the amount at the end to be $1,655.10
