Elizabeth has 8 ounces of chopped vegetables in a mixing bowl. She needs to have a minimum of 50 ounces for a party-sized salad

Lorico [155]

Answer:

the inequality is 50 = 3x -8 because Elizabeth needs 50 ounces but she already has 8 ounces, so you would have to subtract 8 from 50 first. Then to would have to see how many times 3 can fit in the difference

Visual explanation

50 = 3x - 8

take 8 from both sides

42 = 3x

divide 3 from both sides

14 = x

She needs at least 14 cups of chopped vegetables
