Answer: [tex]\$1139[/tex]
Step-by-step explanation:
Given
The original cost of the laptop is [tex]\$1340[/tex]
A sale of 15% is applicable on it
The buyer has to pay 15% less
So, the effective price of the laptop is
[tex]\Rightarrow 1340-15\%\times 1340\\\Rightarrow 1340(1-0.15)\\\Rightarrow 1340\times 0.85\\\Rightarrow \$1139[/tex]
So, the final price of the laptop is [tex]\$1139[/tex].
