I could have sworn I helped you with this yesterday.
You can't say this one is different.
I don't think you did? I don't remember having a problem like this ?
Hang on a minute.
I don't know how you managed to delete those questions you posted yesterday.
I didn't , I don't even know how to delete them ?
If we let: a = number of type A computers b = number of type B computers Then we can produce the following equations: Amount of Computers a + b ≤ 120 Cost of Computers: C(a,b) = 237a + 122b Profit from computers: 22a + 19b ≥ 2400 So now we take the amount equation and the profit equation and solve for a and b: a + b ≤ 120 22a + 19b ≥ 2400 Multiply the first equation by 22 to get: 22a + 22b ≤ 2640 22a + 19b ≥ 2400 Isolate 22a in both equations: 22a ≤ 2640 - 22b 22a ≥ 2400 - 19b Now set: 22a ≤ 22a 2400 - 19b ≤ 2640 - 22b Place like terms on the same side: 22b - 19b ≤ 2640 - 2400 3b ≤ 240 b ≤ 240/3 b ≤ 80 Thus a ≤ 40 since we know that a + b ≤ 120
That's the same solution I typed up yesterday.
That's why I was able to post it so quickly
Thus that proves the question was posted yesterday
Furthermore, since a = 40 and b = 80, we can find the total cost: C(a,b) = 237a + 122b C(40,80) = 237(40) + 122(80) = 19,240
I do remember that . But, I swear I didn't delete anything ? and so you mean to say my teacher gave me the same question for yesterday & today ? lol
After further review, it appears that someone else must have posted the same question.
oh , but is it even possible to delete questions you have asked ?
No, not anymore
However, it is possible to alter your question.
Oh , well thank you for helping me again .
hey , lol . are you in connections acad. ?
