Art [367]

Answer:

25%

Step-by-step explanation:

Given that,

Initial cost of a t-shirt = $30

Final cost of a t-shirt = $37.50

We need to find percent of change. The percentage change in any value is given by :

\%=\dfrac{\text{final value-initial value}}{\text{initial value}}\times 100\\\\=\dfrac{37.5-30}{30}\times 100\\\\=25\%

Hence, the percentage error is 25%.

How do you find the inverse of a exponet
faust18 [17]
"Inverse of an exponent?"  Unsure of what you mean.  Do you want to find the inverse of an exponential function?

Suppose  y = 2e^x.  Find the inverse function:

1.  Interchange x and y:  x = 2e^y
2.  Solve this for y:  ln x = ln 2 + y, so y = ln x - ln 2, or   y = ln (x/2)  (answer)
