Alexandra has a stand in the marketplace where she sells her cumin for 7.20 per kilogram. If she sells 90 kilograms of cumin her
Drupady [299]

Answer:

$234

Step-by-step explanation:

First we need to define profits. Profits are Income minus Expenses:

P = I - E

We know profits are $414, so:

414 = I - E

We also can calculate income, as it is equal to price by the sales:

I = p*Q

Here she sold 90 kgs at $7.20 b kg. So:

I = p*Q = 7.20 * 90 = 648

So, replacing in profits equation:

414 = I - E

414 = 648 - E

If we sum E in both sides:

414 + E = 648 - E + E = 648

414 + E = 648

Now, subtracting 414 in both sides:

414 + E - 414 = 648 - 414

E = 234

So, her expenses are $234

Im confused <br><br><br> khan academy 8th grade
Anit [1.1K]

Answer:

14

Step-by-step explanation:

hi! so the question is asking what h is when you input -18 for x, right?

inputing in this question means to substitute, meaning that in this equation, -18 will take the place of x!

  • let's see what the equation looks like now
  • h = 17 + \frac{-18}{6}
  • easy as that!

now let's do the math :)

  • because of PEMDAS, remember to do the fraction (dividing) first!
  • h = 17 + (-3)

we can change that to --> h = 17 - 3

h = 14

let me know if you're still confused!
