Answer 1

6.40 divided by 4 which is $1.60

Answer 2

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

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 =
`(6.40)/(4)`.

P = $1.60.

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