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.
At 3:05 sam left for his school at speed of 3.2 miles per hour.
After 15 minutes, thus, around 3:20, Al started running after him.
AL caught up after 10 minutes later.
Als speed
=> 3.2 mph * 60 minutes = 192 miles per minute
=> 192 miles per minute / 15 = 12.8 miles
12.8 miles /10 minutes = 1.28 miles per hour is Als speed.
