The equation yˆ=−5.131x 2+31.821x−3.333 approximates the number of people standing in line to catch a commuter train x hours aft
ololo11 [35]
For this case we have the following equation:
 y = -5.131x ^ 2 + 31.821x - 3.333

 When it's 5 a.m. then x = 0
 Therefore, when it is 7 a.m. then x = 2.
 Substituting x = 2 in the equation we have:
 y = -5.131 * (2) ^ 2 + 31.821 * (2) - 3.333

y = 39,785
 Rounding to the nearest whole number:
 y = 40

 Answer:
 
the best estimate for the number of people in line at 7 a.m. is:
 
y = 40

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.
