Elsie pays $8.99 for a one-pound canister of Georgia pecans. Write and solve a proportion to determine the cost of 4

ch4aika [34]

Answer:

$ 35.96

Step-by-step explanation:

Let x be the cost ( in dollars ) of 4 ounces of the pecans,

So, the ratio of the cost and ounces needed = $\frac{x}{4}$

Also, the cost of 1 ounces of pecans is $ 8.99,

Thus, the ratio of the cost and ounces needed = $\frac{8.99}{1}$

Hence, we can write,

$\frac{x}{4}=\frac{8.99}{1}$

Which is the required proportion,

By cross multiplication,

x = 4 × 8.99 = 35.96

Therefore, $ 35.96 is the cost of 4 ounces of the pecans.
