Question

Together, louisa and jill scored more than 30 points in the basketball game. if jill scored 12 points, how many points p did louisa score?
a. p > 18
b. p > 42
c. p < 42
d. p < 18

Answer 1

what this means algebraically:
Louisa + Jill = not 30, but more than 30 (which means its ether < or >)
Jill =12
Louisa + 12 =30 
Louisa  +12 -12 = 30-12  (subtract to isolate Louisa)
Louisa = 18 (more than 18 remember)
The crocodile likes to eat the bigger number.
In this case, since they scored MORE THAN 30 pts, than Louisa's score must be MORE THAN 18. which means that P would be the bigger number.
A. p >18
