Question

IM DESPERATE I would like an explanation to go with the answer. THANK YOUOnly #5 and #6

Answer 1

`\begin{gathered} (10)/(100)*30=3 \\ \text{Therefore, } \\ \text{Sale Price = 30-3=\$27} \end{gathered}`
`\begin{gathered} 4) \\ \text{Discount}=(55-46.75)/(55)*100=15percent \end{gathered}`
`\begin{gathered} 5)\text{Let x be the original price} \\ (x-74.75)/(x)*100=75 \\ x-74.75=0.75x \\ \Rightarrow x-0.75x=74.75 \\ 0.25x=74.75 \\ \Rightarrow x=(74.75)/(0.25)=299 \end{gathered}`

Therefore the original price is $299

`6)\text{ selling price = 152+152}*(50)/(100)=152+76=228`

the selling price is $228
