To get home from school, bob ops four blocks north and three blocks east. what is the straight-line distance between bob’s house in his school?

That's a Pythagorean Theorem application, and this is the first Pythagorean Triple in the book.

If we don't recognize that

we can do the math:

5 blocks

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
