The usual price of a stapler sold at Shop U and V is $20. During a sale, a discount of 20% is given to every stapler sold at Shop U. At Shop V, a discount of 40% is given to the 6th stapler for every 6 staplers sold. How much cheaper would it be if Nicole buys 14 staplers from Shop U instead of Shop V?

	Shop U	Shop V
Price of 1 stapler	80%  $16	100% $20
Every 6th stapler		60% $12

Price of 1 stapler from Shop U in percentage
= 100% - 20%
= 80%

Price of 1 stapler from Shop U at 20% discount
= 80% x 20
= ⁸⁰₁₀₀ x 20 
= $16

Cost of 14 staplers from Shop U
= 14 x 16
= $224

Price of the 6th stapler from Shop V in percentage
= 100% - 40%
= 60%

Cost of 6th stapler at Shop V
= 60% x 20
= ⁶⁰₁₀₀ x 20 
= $12

Cost of 1 set of 6 staplers at Shop V
= 20 x 5 + 12
= $112

Number of sets of 6 for staplers at Shop V
= 14 ÷ 6
= 2 r 2

Cost of 2 sets of 6 staplers at Shop V
= 2 x 112
= $224

Cost of 2 staplers at Shop V
= 2 x 12
= $24

Cost of 14 staplers at Shop V
= 224 + 24
= $248

Amount cheaper if Nicole buys 14 staplers from Shop U instead of Shop V
= 248 - 224
= $24

Answer(s): $24
