Answer: Store B
Step by Step
divide the the normal price of the book by four to get the amount of the book on sale in store B which is $21. To get the answer for Store A divide the normal price of the book by ten then divide the amount you get by 2 and add the two amounts up to get the the amount of the book on sale which is $21.26

Divide 52 by 4 which gives you 13. 13 x 4 = 52
Speed of snail 1 = 3.795 cm/minute
Speed of snail 2 = 4.795 cm/minute
<em><u>Solution:</u></em>
Given that,
Total distance = 189 cm
They crawl towards each other at rates that differ by 1 cm a minute
Let the speed of snail 1 be "x"
Let the speed of snail 2 be "x + 1"
Total time = 22 minutes
Since the snails are moving towards each other,
Speed = x + x + 1 = 2x + 1
<em><u>How fast is each snail crawling?</u></em>

Thus,
Speed of snail 1 = 3.795 cm/minute
Speed of snail 2 = 3.795 + 1 = 4.795 cm/minute
Equation y=3x+5.
Anything with the slope of 3x.
So it could be y+3x+9
