Supermarket big selling:A chocolate bar sell 30$,discount 15%,if you're that menber,then U can also have that discount.Ask how much is it if that you're the menber and U less pay that $
ans:

the watermalon price is=5.6*6.3=35.28=35.3(take the num. to 0.1)
The price which that U are the menber=30*85%*85%=21.675$
