The cost of a color film for 12 photographs is normally $1.08. Additionally the cost of printing the 12 photographs is normally $1.92.
\n" ); document.write( "a) Show that the total cost of each photograph is normally 25 cents,
\n" ); document.write( "let us solve in cents.
\n" ); document.write( "...
\n" ); document.write( "cost of film $1.08 = 108 cents
\n" ); document.write( "cost of printing = 192 cents
\n" ); document.write( "Total= 300 cents
\n" ); document.write( "..
\n" ); document.write( "cost per photograph = 300/25
\n" ); document.write( "=25 cents
\n" ); document.write( "...\r
\n" ); document.write( "\n" ); document.write( "b) One shop decides to sell 3 films for the price of 2 films. The cost of printing remains $1.92 for each film. Calculate the total cost of each photograph at this shop.
\n" ); document.write( "3 films cost 108*2 = 216 cents
\n" ); document.write( "printing = 192*3=576 cents
\n" ); document.write( "Total: 216+576=792 cents
\n" ); document.write( "Cost per photograph = 792/36
\n" ); document.write( "Cost per photograph = 22 cents
\n" ); document.write( "...
\n" ); document.write( "c) A second shop keeps the price of the film $1.08 and offers a reduction of 25 % off the cost of printing. Calculate the total cost of each photograph at this shop.
\n" ); document.write( "..
\n" ); document.write( "Cost of film = 108 cents
\n" ); document.write( "cost of printing = 192 less 25%
\n" ); document.write( "cost of printing = 192 *0.75 = 144 cents
\n" ); document.write( "Total cost for 12 photographs = 108+144=252 cents
\n" ); document.write( "cost per photograph = 252/12
\n" ); document.write( "cost per photograph = 21 cents
\n" ); document.write( "...
\n" ); document.write( "d) Calculate the percentage reduction in the total cost, of a photograph obtained from the second shop.
\n" ); document.write( "22-21 =1 cent cheaper
\n" ); document.write( "1/22*100 =4.54% reduction
