Alexandria requires 55 rows to use all the shells.
Step-by-step explanation:
Given:
Number of Shells = 329
Number of shells in each row = 6
We need to find the number of rows she need if she wants to use all the shells.
Solution:
Now we know that;
number of rows she needs can be calculated by Dividing Number of Shells with Number of shells in each row.

Answer:
45
Step-by-step explanation:
first create a proportion.
40/100 = 18/x
you're trying to find x, the original price, so to find x you'll need to cross multiply. 18 times 100 divided by 40, which is 45.
The original price was $45
A point is X because X and Y and Z are al points
The problem statement tells us ...
... paycheck = 4000 + 0.09×sales
and that the paycheck amount is 11650. Substituting that into the above equation and solving for sales, we have ...
... 11650 = 4000 + 0.09×sales
... 7650 = 0.09×sales . . . . . . . . . . subract 4000
... 7650/0.09 = sales = 85000 . . . divide by 0.09
John's sales during that month were $85,000.
