Omar uses the equation y = 2.89x to determine the total cost, y, in dollars, for x pounds of potato salad. Which statement about the cost of potato salad at Barry’s and Omar’s sandwich shops is true?
A. The cost per pound at Barry’s sandwich shop is less than the cost per pound at Omar’s sandwich shop.
B. The cost per pound at Omar’s sandwich shop is less than the cost per pound at Barry’s sandwich shop.
C. The cost per pound at the cheaper sandwich shop depends on how many pounds of potato salad a customer purchases.
D. It is impossible to determine which sandwich shop charges less per pound based on the given information.
The correct answer is: A. The cost per pound at Barry’s sandwich shop is less than the cost per pound at Omar’s sandwich shop.
Explanation: Omar’s equation y = 2.89x indicates that the cost per pound of potato salad at his shop is $2.89. To determine whether Barry’s sandwich shop is cheaper, we would need information about the price per pound at Barry’s. However, since we only know the cost at Omar’s, we can’t definitively compare unless we have that additional information about Barry’s price. If we assume Barry’s price per pound is less than $2.89, then option A would hold true.
