250 people went to a “couples party” party at 9am. if 70 people left at 11pm how many couples remained at the party?

90 couples or 180 ppl

Step-by-step explanation:

lets take "x" as the couples who remained at the party

we start out with 250:

250

but by the time it is 11pm, 70 people have left the party

since it is a couples party we need to divide by two to account for the couples

=x

250-70=180

180/2=90

so 90 couples or 180 ppl

hope this helps
