Final answer:
To find the cost of a 35-ounce package of cookies with the same cost per ounce as a 10-ounce package, use a proportion to solve for the unknown cost.
Step-by-step explanation:
To find the cost of a 35-ounce package of cookies, assuming the same cost per ounce as the 10-ounce package, we can set up a proportion. Let's call the cost of the 35-ounce package 'x'.
Using the proportion: 10 ounces / $2 = 35 ounces / x
To solve for 'x', we can cross-multiply and then solve for 'x'.
10x = 35 * 2 = 70
x = 70/10 = $7
Therefore, a 35-ounce package of cookies would cost $7.
