A box of erasers cost 4 dollars. A box of pencils cost 6 dollars more. Darwin spent 240 dollars on some boxes of erasers and pencils. The ratio of the number of pencil boxes to the number of eraser boxes was 4:5. How many boxes of pencils did he buy?
Hint: Supppose that Darwin bought x eraser boxes, then he bought \(\frac{4}{5}x\) pencil boxs. (\(x\in N,x>0\)
Because Darwin spent 240 dollars so we have equation:
\(4x+\left(4+6\right).\frac{4}{5}x=240\)
\(\Rightarrow12x=240\Rightarrow x=20\)
So Darwin bought 20 eraser boxes and 16 pencil boxes.
Have a good time :))
