What type of exponential equation is shown? y = c(1 - r)t exponential growth compound interest exponential decay quadratic

Exponential Decay or Growth

Step-by-step explanation:

represents an exponential.

When r is greater than 0 but less than 1, the function decays by decreasing the values through the rate.

When r is less than 0 or negative, the function grows by increasing the values through the rate.

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
