I really need help and i gotchu wit a lot of points if you can help me

i) C= $14.99 k + $24

ii) $93.97

Step-by-step explanation:

Let the number of models be represented by k

Let the amount spent on books to be$24

The equation that represent amount spent in the mall is given as;

C= $14.99 k + $24   where ;

C= the equation for the total amount spent in the mall

k = the number of plane models

ii)

Using the equation : C= $14.99 k + $24    and if k = 3 and the amount spent on the store is $25  then ;

C= $14.99 * 3 + $24 = $44.97 + $24 = $68.97

C+ 25 = $68.97 + 25 =$93.97

is there answer choices?
