Answer:

  Store A has a better deal because $402.90 is less than $404.10.

Step-by-step explanation:

<u>Store A</u>

The $25 off coupon reduces the price to ...

  $499 - 25 = $474

The discount from this amount is 15%, so is ...

  $474 × 0.15 = $71.10

The final amount paid is then ...

  $474.00 -71.10 = $402.90

(<em>Side note</em>: you can select the correct answer at this point, because only one answer shows this value.)

___

<u>Store B</u>

After the $20 off coupon, the price is ...

  $469 -20 = $449

The additional 10% discount amounts to ...

  $449 × 0.10 = $44.90

So, the final price is ...

  $449.00 -44.90 = $404.10

___

Now, you know that Store A offers the better price because $402.90 is less than $404.10.

Answer:  \bold{a)\quad 51, 54, 57\qquad a_n=a_{n-1}+3}

               \bold{b)\quad 250, 625, 1562.5\qquad a_n=(2.5)a_{n-1}}

<u>Step-by-step explanation:</u>

a) This is an arithmetic sequence where 3 is added to the previous term.

48 + 3 = 51

              51 + 3 = 54

                            54 + 3 = 57

The recursive formula for this sequence is:  a_n = a_{n-1}+3

*****************************************************************************************

b) This is a geometric sequence where 2.5 is multiplied to the previous term.

100(2.5) = 250

                250 (2.5) = 625

                                    625(2.5) = 1562.5

The recursive formula for this sequence is: a_n=(2.5)a_{n-1}
