write an inequality to represent this siutation.

Answer 1

An inequality:
136 + x ≥ 189
x ≥ 189 - 136
x ≥ 53
Answer:
He must earn at least $53.

Answer 2

Answer: $53

Explanation:

Given: Earning of Arthur in three weeks = $136

Let x be the money he earn in one more week.

If he needs at least $189 to buy the new coat that he wants for school.

Then it gives the inequality
`136+x\geq 189`

Subtract 136 from both sides of the inequality, we get

`x\geq 189-136\\\Rightarrow\ x\geq 53`

Hence, Arthur must earn $ 53 in the next week.
