Question

Travis is buying Mushrooms at the grocery store mushrooms cost five dollars for 9 ounces how much will 13 ounces of mushroom cost to the nearest cent

Answer 1

Explanation:

9 oz cost $5 therefore you want to find the cost per oz which would be $5/9oz= 0.55555556 per oz

0.55555556 x 13oz = $7.222222 which is $7.22

Answer 2

For this case we make a rule of three, based on the fact that 9 ounces of mushrooms cost $ 5.

9 oz --------------> 5 $

13oz ------------> x

Where "x" represents the amount of dollars that cost 13 ounces of mushrooms.

`x = \frac {13 * 5} {9} = \frac {65} {9} = 7.222222`

Rounding out, we have that 13 ounces of mushrooms cost $ 7 with 22 cents.

Answer:

$ 7 with 22 cents
