Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. after collecting only three shark’s teeth, sarah decides to share the opportunity with her friend john. sarah can find shark teeth twice as fast as john, but she can earn even more money with his .

5(2j + 3 + j)
j = 2
part 3: finish the story
write a few sentences to end sarah’s story. how many shark teeth did she find? how many shark teeth did john find? how much money did sarah earn?

If I'm right then she found 45 teeth and she made $225, I don't know if I'm right but I think I am.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

207/8 is the right
