Zack needs $299.99 to buy the new bike he wants. he has saved $150 so far toward the new bike. from this week on, he will save $12.50 per week toward the new bike. ten weeks from now, how much more money will he still need to save to buy the bike?

$24.99 is the more money will Zack still need to save to buy the bike .

Step-by-step explanation:

As given

Zack needs $299.99 to buy the new bike he wants. he has saved $150 so far toward the new bike.

From this week on, he will save $12.50 per week toward the new bike. ten weeks from now .

Equations becomes

Money Zack have and he saved in 10 weeks = Saved amount + Save per week × Number of weeks .

Putting all the values in the above

Money Zack have and he saved in 10 weeks = 150 + 12.50 × 10

                                                                          = 150 + 125

                                                                         = 275

Money Zack will save to buy the bike = Bike Price - Money Zack have and he saved in 10 weeks .

Putting values in the above

More money Zack will save to buy the bike = $ 299.99 - $275

                                                               = $ 24.99

Therefore the $ 24.99 is the more money will Zack still need to save to buy the bike .

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
