Jason's part-time job pays him $105 a week. If he has already saved $325, what is the minimum number of weeks he needs to work i

Art [367]

Jason's part-time job pays him $105 a week

He got an amount of 105 dollars per week

Thhe cost price of the Dit bike = $900

The saving amount he had = $325

So, The amount he require more is the difference in the cost price of the bike to the saving amount

Require amount = 900-325

Require Amount = $575

Since he get the $105 per week

We need to find the number of weeks to get an amount of $575

So, divide the total required amount by the amount in one week he get

$\begin{gathered} \text{ Number of w}eek\text{ =}\frac{Total\text{ Amount}}{Amount\text{ he get p}er\text{ week}} \\ \text{Number of w}eek\text{ =}\frac{575}{105} \\ \text{Number of w}eeks\text{ =}5.47 \\ \text{Number of we}eks\text{ }\approx6 \end{gathered}$

So, he neeed to wokr for 6 weeks to pay for the dirt bike

For this problem, we are going to use the Remainder Theorem. This says that for $x - n$ to be a factor of a polynomial $p(x)$ , then $p(n) = 0$ . Essentially, it says that $x - n$ is a factor if when you substitute $n$ into the polynomial you get a result of 0.

Thus, in our case, when we substitute $x = 2$ into the polynomial, we should get an answer of 0 if $x - 2$ is a factor of the polynomial. Given this information, we can solve for $c$ :
