Question

Arthur earn $136 in three weeks he goes back to school in one he needs at least $189 in a new coat that he wants for school how much must Arthur in the next week

Answer 1

189-136 equal 53 thats your answer

Answer 2

What you have to do is find out how much he made each week. Because you know how much he made in 3, you can divide 136 into 3. 


136/3=45.333...

so the next thing you'd have to do is find out how much he needs in addition. So you do: 189-136= how much more he needs in the next week. 

189-136= 53 

hope thats what you wanted, if not, private message me and I will personally help you find the better answer.
