 
 <prompt> Thomas don save $40 for bank every month for six years. Im friend Joseph don dey save 2/5 times less money every month. How much money dem get for their savings account together? <response>: Thomas don save money for six years, and since each year get 12 months, e don save money for 6*12 = 72 months.
Since Thomas dey save $40 for bank every month for six years, e don save 72*$40 = $2880
Joseph dey save 2/5 times less money per month pass Thomas, meaning say e dey save 2/5*$40 = $16 less every month.
The total amount of money wey Joseph dey save every month na $40-$16 = $24
For six years, Joseph don save $24*72 = $1728
Together, dem don save total of $2880+$1728 = $4608

The final answer: 4608.
