Answer:
$147
Step-by-step explanation:
The computation of the price of the sofa after two weeks is shown below:
For one week it would be
= Orginal price × (1 - reduced percentage)
= $300 × (1 - 0.30)
= $210
Now for the second week, it would be
= One week price × (1 - reduced percentage)
= $210 × (1 - 0.30)
= $147
Therefore the price of the sofa after two weeks is $147 and the same is to be considered
Your answer should be 93 because 7 times 7.5 is 52.5 and 9 times 4.5 is 40.5 40.5+52.5=93!
