Since Ethan orders 5 boxes of paper clips, and each box costs 15.40 pounds, then you have:

15.40 x 5 =77.00 pounds worth of paper clips that Ethan buys.

Since all purchases between 55.00 and 79.99 pounds, he gets a discount of 6.50%, it therefore follows that : 77 x 6.50% =5.01 pounds that Ethan gets in discount. So, that:

77 - 5.01 =71.99 - Total cost of 5 boxes of paper clips.

His total order at the regular price  =  5 (15.40)  = £ 77

 

So....he gets a  6.5%  discount   =    93.5%  of the regular cost  =  .935

 

So.....the amount of the discount  =

 

77  -  .935 (77)   =  £ 5.005  =  £ 5.01   ( rounded )
