A wholeseller sells a packet of biscuits for 10 and a pack of 10 packets of biscuits for 85. A school Canteen makes an order of 87 packets of biscuits.How much minimum amount should they pay for their order?​

Answer 1

1 packet of biscuits= 10

10 packet of biscuits= 85

therefore , 80 packet of biscuits= 85x80

= 680

7 packet biscuits = 70

therefore total bill = 70 + 680

=750
