I have tried google. Nothing shows up

0.05(X) + 0.04(X-1500)=141

solve for X d thus X-1500

0.09 X =  141 + 60 = 201

X = 2233 and x - 1500= 733.

Check 0.05(2233) + 0.04(733) = 141  Yes.

First line should have printed as 0.05 X + 0.04(X-1500) = 141

Where does the 1500 come from?

anonymous · Answer

It says in the book that the answer is $2100 at 5%, and $900 at 4%????

anonymous · Answer

My error. I should have used 1200, not 1500. I misread it. Sorry. Replace my 1500 with 1200 and you will get the right answer.
