Answer 1

First you have to calculate total cost of speakers. This would be equal to. 2275+ 3×225.

Now divide this total price by 3 to get value of each speaker.

let it be x.
First speaker was sold at 5% loss. i.e. at 95%.
.: proce of selling price speaker is 95x/100. Calculate the value. Let it be y.

Now you want to get profit of 10%, i.e. you have to sell tje speakers at 110%. Tjis value would be equal to 3x×110/100. Let it be z.

Now subtract y from z to get remainig value. This will be the selling price of the remaining two speakers.

Divide this valie by 2 to get price of each speaker.

Hope this helps!
