Answer 1

Answer:

Let each pencil cost $x. Now as per question, if he had paid $1 less for each pencil he would have got 5 pencils more.

Let each pencil cost $x. Now as per question, if he had paid $1 less for each pencil he would have got 5 pencils more.So, 60/x-1 - 60/x = 5 …..(1)

Let each pencil cost $x. Now as per question, if he had paid $1 less for each pencil he would have got 5 pencils more.So, 60/x-1 - 60/x = 5 …..(1)=> 60x -60x+60= 5x² -5x

Let each pencil cost $x. Now as per question, if he had paid $1 less for each pencil he would have got 5 pencils more.So, 60/x-1 - 60/x = 5 …..(1)=> 60x -60x+60= 5x² -5x=> 5x²-5x -60=x² -x - 12 Lhs

Let each pencil cost $x. Now as per question, if he had paid $1 less for each pencil he would have got 5 pencils more.So, 60/x-1 - 60/x = 5 …..(1)=> 60x -60x+60= 5x² -5x=> 5x²-5x -60=x² -x - 12 Lhs=>》x²- x -12=> x²-4x +3x -12

Let each pencil cost $x. Now as per question, if he had paid $1 less for each pencil he would have got 5 pencils more.So, 60/x-1 - 60/x = 5 …..(1)=> 60x -60x+60= 5x² -5x=> 5x²-5x -60=x² -x - 12 Lhs=>》x²- x -12=> x²-4x +3x -12x(x-4)+3(x-4)

Let each pencil cost $x. Now as per question, if he had paid $1 less for each pencil he would have got 5 pencils more.So, 60/x-1 - 60/x = 5 …..(1)=> 60x -60x+60= 5x² -5x=> 5x²-5x -60=x² -x - 12 Lhs=>》x²- x -12=> x²-4x +3x -12x(x-4)+3(x-4)X=4 as x cannot be negative . This $4 is the cost of each pencil and for $60 initially 60÷4 = 15 pencils could have been got.
