solong [7]

Answer:

A. 64

Step-by-step explanation:

The shoes are 80 dollars.  We get a 20% discount

Discount = 80*20%

                = 80*.20

                  =16

The sales price = original price less the discount

James is buying a table.He finds the same table for sale in two different shops.
mina [271]

"Table World" is quoting a better price

<u>Step-by-step explanation:</u>

The shop "Table World" is quoting a price of 140 inclusive of 17.5% VAT

that means 140 is the final price a customer needs to pay.

                       

While other shop"Tables R us" is quoting a price of 120 without VAT

so we need to add VAT in the price to find out the final price

                                           price+VAT on the price

                                          =120+120*(17.5/100)

                                          =120+120*0.175

                                          =120+21

               so final price      =141

so comparatively "Table World" is quoting a better price
