Answer:
<u>The correct answer is B. $310 at $2 per kilogram</u>
Step-by-step explanation:
1. Let's find out the maximum profit Ms. Ortiz can make with a loaf of tomatoes:
function p(x)=–80x² + 320x – 10
For x = 1, price per kilogram of tomatoes would be: 4 - x = 3
–80x² + 320x – 10, replacing with x = 1
-80 * 1² + 320 * 1 - 10 = -80 + 320 - 10 = 230
For x = 2 price per kilogram of tomatoes would be: 4 - x = 2
–80x² + 320x – 10, replacing with x = 2
-80 * 2² + 320 * 2 - 10 = -320 + 640 - 10 = 310
For x = 3, price per kilogram of tomatoes would be: 4 - x = 1
–80x² + 320x – 10, replacing with x = 3
-80 * 3² + 320 * 3 - 10 = -720 + 960 - 10 = 230
<u>The correct answer is B. $310 at $2 per kilogram</u>
