Greg bought 4 notebooks for $6.40. which equation can be used to determine the price, p, in dollars, of 1 notebook?

Equation : 4 × p =  $6.40 and P = $1.60.

Step-by-step explanation:

Given  : Greg bought 4 notebooks for $6.40.

To find : Which equation can be used to determine the price, p, in dollars, of 1 notebook.

Solution : We have given that

Cost of 4 notebook = $6.40.

Cost of 1 notebook represent by p

We can write 4 as 4 × 1

Cost of 4  notebook = $6.40.

Cost of 1 notebook represent by p

Then , 4 × p =  $6.40.

On dividing by 4 both sides

So,  P =   .

P = $1.60.

Therefore,  Equation : 4 × p =  $6.40 and P = $1.60.  

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
