Answer:

  • See below

Step-by-step explanation:

Initial price of both machines is $360

Price after 30% mark down:

  • 360 - 30% =
  • 360*0.7 =
  • 252

Price after 10% and then 20% mark down:

  • (360 - 10%) - 20% =
  • 360*0.9*0.8 =
  • 360*0.72 =  
  • 259.20

The sale price of the first washing machine is lower:

  • $252 < $259.20

Answer:

The sale price of the first washing machine is $252

Step-by-step explanation:

First washing machine

Given information:

  • Selling price = $360
  • Marked down by 30%

If the washing machine is marked down by 30%, the sale price is 70% of the original selling price as 100% - 30% = 70%.

To find the sale price, calculate 70% of $360:

[tex]\begin{aligned}\implies \sf 70\% \:of\: 360 & = \sf 0.7 \times 360\\& = \sf 252 \end{aligned}[/tex]

Therefore, the sale price of Washing Machine 1 is $252.

Second washing machine

Given information:

  • Selling price = $360
  • Marked down by 10% with an additional 20% off.

If the washing machine is marked down by 10%, then has an additional discount of 20% applied, the sale price can be calculated by first finding 90% of the selling price, then finding 80% of the reduced price:

[tex]\begin{aligned}\implies \sf 90\% \:of\: 360 & = \sf 0.9 \times 360\\& = \sf 324\end{aligned}[/tex]

[tex]\begin{aligned}\implies \sf 80\% \:of\: 324 & = \sf 0.8 \times 324 \\& = \sf 259.2\end{aligned}[/tex]

Therefore, the sale price of Washing Machine 2 is $259.50.

Joanne should buy the first washing machine rather than the second, as after the discounts are applied, the first washing machine is cheaper than the second by $7.50.
