Answer:
A: Price of TV, when purchased online=$1120.5
Price of TV, when purchased at the superstore=$1203.5
B: Difference= $83.
Step-by-step explanation:
We have been given that a TCL 6 series 2018 Roku TV can be purchased from the manufacturer for $830. A certain online retailer has a standard markup of 35%, and a certain superstore has a standard markup of 45%.
A: Let us find price of TV, when purchased online.
![\text{Price of TV, when purchased online}=\text{Manufacturing price+ Mark up of 35 percent}](https://tex.z-dn.net/?f=%5Ctext%7BPrice%20of%20TV%2C%20when%20purchased%20online%7D%3D%5Ctext%7BManufacturing%20price%2B%20Mark%20up%20of%2035%20percent%7D)
![\text{Price of TV, when purchased online}=830+ 830*\frac{35}{100}](https://tex.z-dn.net/?f=%5Ctext%7BPrice%20of%20TV%2C%20when%20purchased%20online%7D%3D830%2B%20830%2A%5Cfrac%7B35%7D%7B100%7D)
![\text{Price of TV, when purchased online}=830+ 830*0.35](https://tex.z-dn.net/?f=%5Ctext%7BPrice%20of%20TV%2C%20when%20purchased%20online%7D%3D830%2B%20830%2A0.35)
![\text{Price of TV, when purchased online}=830+ 290.5](https://tex.z-dn.net/?f=%5Ctext%7BPrice%20of%20TV%2C%20when%20purchased%20online%7D%3D830%2B%20290.5)
![\text{Price of TV, when purchased online}=1120.5](https://tex.z-dn.net/?f=%5Ctext%7BPrice%20of%20TV%2C%20when%20purchased%20online%7D%3D1120.5)
Therefore, the price of TV, when purchased online is $1120.5.
Now let us find price of TV, when purchased at superstore.
![\text{Price of TV, when purchased at the superstore}=\text{Manufacturing price+ Mark up of 45 percent}](https://tex.z-dn.net/?f=%5Ctext%7BPrice%20of%20TV%2C%20when%20purchased%20at%20the%20superstore%7D%3D%5Ctext%7BManufacturing%20price%2B%20Mark%20up%20of%2045%20percent%7D)
![\text{Price of TV, when purchased at the superstore}=830+830*0.45](https://tex.z-dn.net/?f=%5Ctext%7BPrice%20of%20TV%2C%20when%20purchased%20at%20the%20superstore%7D%3D830%2B830%2A0.45)
![\text{Price of TV, when purchased at the superstore}=830+373.5](https://tex.z-dn.net/?f=%5Ctext%7BPrice%20of%20TV%2C%20when%20purchased%20at%20the%20superstore%7D%3D830%2B373.5)
![\text{Price of TV, when purchased at the superstore}=1203.5](https://tex.z-dn.net/?f=%5Ctext%7BPrice%20of%20TV%2C%20when%20purchased%20at%20the%20superstore%7D%3D1203.5)
Therefore, the price of TV, when purchased at the superstore is $1203.5.
B: Now let us subtract 1120.5 from 1203.5 to find difference between the prices at the superstore and online.
![\text{Difference of prices}=1203.5-1120.5](https://tex.z-dn.net/?f=%5Ctext%7BDifference%20of%20prices%7D%3D1203.5-1120.5)
![\text{Difference of prices}=83](https://tex.z-dn.net/?f=%5Ctext%7BDifference%20of%20prices%7D%3D83)
Since 45% markup is greater than 35% of markup, therefore, price of TCL 6 series TV is $83 greater while buying from superstar than buying online.
