Answer 1

The cost of 4 ounces of the pecans is $2.24.

Explanation:

Given:

Eliseo pays $8.99 for a one-pound canister of Georgia pecans.

Now, to solve a proportion to determine the cost of 4 ounces of the pecans she needs for a particular recipe.

Let the cost of 4 ounces of the pecans be
`x.`

1 pound = 16 ounces.

So, using unitary method we get cost of 1 ounces:

Cost of 16 ounces of the pecans = $8.99.

Cost of 1 ounces of the pecans = $8.99 ÷ 16 = $0.56.

According to question we set proportion:

`4:x=1:0.56`

So, to get by cross multiplication method:

`(4)/(x) =(1)/(0.56)`

By cross multiplying we get:

`2.24=x`

`x=2.24`

Thus, the cost of 4 ounces of the pecans is $2.24.
