Hi mathsguru, pls kindly help me with this question:-


A delivery service charges $18 for each item delivered safely to a customer, but it has to pay $38 for every item that is damaged during delivery. If a customer pays a total of $48376 for an order of 3988 glass sculptures, how many glass sculptures are delivered safely without damage?

Thank you very much.

equation of line parallel to AB and passing thru the origin is

y = -1.4x
