Amount of sales of newspapers for the month of January = $8341.50 Percentage of profit for which the newspaper is sold = 0.5% Then Amount of profit made in the month of January = 0.5% * 8341.50 dollars = (0.5/100) * 8341.50 dollars = 4170.75/100 dollars = 41.707 dollars = 41.71 dollars So the shop makes a profit of $41.71 in the month of January by selling newspapers worth $8341.50. I hope the procedure is perfectly clear for you to understand.
A and b are already there but to get c you just have to move 6 to the other side by subtracting it from the right side and adding it to the end of the left side.
