Hey guys can u me with this show me step by step and show me the answer

She needs to sell over 20 and she has sold 8, so 20 - 8 = 12
That means she has to sell greater than or equal to 12 buckets of popcorn.
The answer is b≥12

Kimberley has sold 8 buckets, 8 will act as the constant in the inequality.
She needs to sell b buckets for reaching the target. b will be the variable in the inequality.
She needs to sell at least 20 buckets. Use symbol ≥ in the inequality, it means the number of buckets should be equal or higher than 20. 20 acts as the constant.

The inequality will be
8 + b ≥ 20

 the variable
      ↑
8 + b ≥ 20
↓           ↓
the constant

If the question only asks the form of the inequality, stop right here.


But, if you need to solve the inequality, follow these steps.
8 + b ≥ 20

substract 8 from both side
8 - 8 + b ≥ 20 - 8
b ≥ 12
Kimberley needs to sell at least 12 buckets

The summary
The inequality will be
8 + b ≥ 20

 the variable
      ↑
8 + b ≥ 20
↓           ↓
the constant

Work on the inequality
substract 8 from both side
8 - 8 + b ≥ 20 - 8
b ≥ 12
Kimberley needs to sell at least 12 buckets

Answer: 900°

good luck on your studies! : )
