Jacob is saving to buy an MP3 player that costs $195. He earns $225 a week at a part-time job. His expenses are $180 a week. If he currently has saved $55, how many more weeks will it be before he can buy the MP3 player?

Jocab will take 4 more weeks to buy that MP3 player.

Step-by-step explanation:

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.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

the answer is: the length is 5/6 yards.
