To find Emma's profit, you will calculate her cost for all the items and the amount of money she collected when she resold the items.
Subtract the two amounts to find her profit or how much money she made when she sold them.
Amount Emma paid: (2 x 35) + (3 x 75) + (5 x 4) = $315
Amount the items sold for: (2 x 65) + (3 x 136) + (5 x 15) = $613
$613 - $315 = $298
Emma made $298 in profit on her items.
Answer:
The answer is the first choice, x < −4.
Step-by-step explanation:
Let's solve your inequality step-by-step.
2x−2>4x+6
Step 1: Subtract 4x from both sides.
2x−2−4x>4x+6−4x
−2x−2>6
Step 2: Add 2 to both sides.
−2x−2+2>6+2
−2x>8
Step 3: Divide both sides by -2.
x<−4
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(3, 0)
Equation Form:
x = 3, y = 0
