Answer:

4. $130.50

Step-by-step explanation:

Sorry, but I only know for no.4 which is $130.50.

Explanation: 18 hours is 20 percent more than 15 hours.


So all we have to do is multiply 1.2 to 108.75, since multiplying 1.2 is the equivalent to 20 percent.

Which then is why I get the answer of $130.50.

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
