Joe earned 2,100$. He spent 1/5 on rent and 1/4 on food. How much money did he have left?
LUCKY_DIMON [66]

The amount of money that Joe has left is $1155

<h3>How to calculate the amount of money left ? </h3>

Joe earned $2100

He spent 1/5 of the money on rent

1/5 × 2100

= 420

$420 was spent on rent

He spent 1/4 of the money on food

= 1/4 × 2100

= 525

$525 was spent on food

The amount of money left can be calculated as follows

Total amount spent = 525 + 420

                   = 945

Amount left= 2100 - 945

= 1155

Hence Joe has $1155 left
