2 Step-by-step explanation:
in the places there is X you put -3 , -3 squared minus 7 is equal to 9 , 9-7 is equal to 2
Step One
Find the cost of one bottle
12 bottles cost 9.25 pounds.
1 bottle costs x
12 / 1 = 9.25/x Cross multiply
12*x = 1 * 9.25 Divide by 12
x = 9.25 / 12
x = 0.77
Remark
0.77 pounds sterling = 77 pennies
Step Two
find the profit on the sale of one bottle
100 - 77 = 23 pennies
Step Three
Find the % profit on one bottle.
% Profit = (profit on one bottle / Cost of 1 bottle.) * 100%
% Profit = (23 / 77) * 100
% Profit = 29.87% <<<<<<<< Answer.
Answer: The Answer Is C.
Step-by-step explanation:
When you divide each of them you will notice that C costs the least.
For choice A when you 5 by 3.25 you will get 0.65.
For choice B when you divide 8 by 6.10 you will get 0.7625
For choice C when you divide 12 by 7 you will get 0.5833.....
For choice D when you divide 10 by 6.44 you will get 0.644.
