Answer 1

Answer:

Answer:

The correct answer is B. $310 at $2 per kilogram

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

The correct answer is B. $310 at $2 per kilogram

Answer 2

Answer:

Answer:The correct answer is B.) $310 at $2 per kilogram

Please help me i am in trouble

Answers

1/6 is your answer hope i could help:)

I'm not quite sure what the above answer is talking about, but we can work this out by working the problem backwards like so:
175 + 60 = 235
235 x 2 = 470
470 - 40 = 430
430 x 2 = 860
Therefore he had 860 paperclips to start with :))
