Answer:
The correct answer is 15 potatoes.
Step-by-step explanation:
To solve this problem, we can determine the unit rate and use proportions. We know that Sarai needs 6 potatoes for 16 latkes. We want to know how many potatoes she will need to make 40 latkes. Let's call this unknown value x. We can set up the following equation:
6 potatoes/16 latkes = x potatoes/40 latkes
To solve this equation, we can first simplify the left side to find the unit rate.
3 potatoes/8 latkes = x potatoes/40 latkes
To solve, we can recognize that 40 latkes is 5 times the amount shown in the unit rate (8 latkes), which means that we need 5 times the amount of potatoes.
3 potatoes * 5 = 15 potatoes
Therefore, the correct answer is 15 potatoes. Note that you could have also just solved the equation for x to find your answer as well.
