Answer: $53


Step-by-step 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 [tex]136+x\geq 189[/tex]

Subtract 136 from both sides of the inequality, we get

[tex]x\geq 189-136\\\Rightarrow\ x\geq 53[/tex]

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