Amount of money Julian can spend on trip= $1250
Amount spent on airfare = $358
Money left for trip = Total money - money spent on airfare= 1250 - 358= $892
So writing an inquality ,
[tex] x\leq 1250-358 [/tex]
where x is amount he can spend on trip.

[tex] x\leq 892 [/tex]
So he can spend less than or equal to $892 on the trip.
