Question 1158023
{{{(4x)/4=160}}}.... four passengers weigh an average of 160 pounds
Multiply both sides by four to determine the total weight of the four passengers. It will be {{{640 pounds}}}.


y=possible weight of cargo
{{{640+y <= 1142}}}... the weight limit for all passengers and cargo is 1142 pounds

so, {{{y<=502}}} when you subtract 640 from both sides.


The maximum weight of the cargo is {{{502 pounds}}}
