Question from Abeth, a teacher:

The average weekly income of MJ for the first three weeks of August was 3,600 and his average weekly income for four weeks is 3950. Find his income on the fourth week of August.


If MJ made $\$T$ in the first three weeks then $\large \frac{\$T}{3} = \small \$3,600.$ What is $T?$ What is the total that MJ made in all four weeks? How much did he make in the fourth week?
