What is the growth factor associated with the following growth rate: 30% decrease Your answer should be typed as a decimal.

Given:

Growth rate = 30% decrease

To find:

The growth factor associated with the given growth rate.

Solution:

The general exponential function is:

Where, a is the initial value, r is the growth rate in decimal and is the growth factor.

It is given that the growth rate is 30% decrease. So,

Now,

Therefore, the growth factor is 0.7.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
