Arare coins value can be modeled with the equation w(x)=250(1.085)^x where x represents the number of years since the coin was first purchased and and w(x) is the current worth of the coin. explain what 250 and 1.085 represent in the context of the problem.

250 is the initial value and 1.085 is the growth factor.

Step-by-step explanation:

A rare coin's value can be modeled with the equation

................. (1)

where x represents the number of years since the coin was first purchased and W(x) is the current worth of the coin.

Now, this equation (1) is an exponential growth function.

Here, 250 is the initial value as we get W(x = 0) = 250 and 1.085 is known as the growth factor which can not be equal to 1. (Answer)

its 8

step-by-step explanation:

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
