Jocab will take 4 more weeks to buy that MP3 player.
<u>Step-by-step explanation:</u>
Given:
Cost of MP3 player = $ 195
Earning per week = $ 225
Expenses per week = $ 180
To Find:
Weeks still required to save money for buying MP3 player.
Formula to be used:
Savings per week = Earning - Expenses
Solution:
Savings per week = Earning - Expenses
= $ 225 - $ 180 = $ 45
Already saved = $ 55
Need to save = $ 195 - $ 55 = $ 140
So for 4 weeks savings = $ 45 × 4 = $ 180
Thus Jocab will take 4 more weeks to buy that MP3 player.

The derivative of the function is the slope
2x^2 - x -1 take derivative ( f ' )
4x -1 equate to 7
7 = 4x -1
x = 2 sub into the original equation to find y = 5
