Yacob wants to buy some chocolates for his friends. If he spends $5 on each

friend, he will have $20 left. If he spends $7 on each friend, he will have $4 left.

How much money does Yacob have?

If you take the remainder one way ($20.00) and subtract the remainder when done the other way ($4.00),

you get $20.00 - $4.00 = $16.00.

 

The amount spent per person differs by $2.00 ($7.00 - $5.00 = $2.00).

 

Divide the $16.00 by $2.00 and you get 8.

 

This means that there are 8 friends.

 

8 x $5.00 + $20.00  =  $40.00 + $20.00  =  $60.00

8 x $7.00 + $4.00  =  $56.00 + $4.00  =  $60.00.

 

Yacob has $60.00.

His friends => x

 

5x + 16 = 7x

 

x = 8

 

Yacob has $60
