Question

Brad buys a pack of 12 bottles of energy drink for £9.25

Answer 1

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.
