Question

250 people went to a "couples only" party at 9pm.70 people left at 11pm, how many couples stayed at the party?

Answer 1

90 Couples

Explanation:

There were 250 total people at the beginning at the party. 70 people left at 11pm.

Subtract 70 from 250:

`250-70=180`

There were 180 people that stayed.

A couple consists of two people. The question asks how many couples stayed at the party, not people.

Divide 180 by 2:

`(180)/(2)= 90`

There would be 90 couples that stayed at the party.

Answer 2

90

Explanation:

Total People = 250

Left the party at 11 pm = 70

Stayed = 250-70

=> 180

Couples that stayed = 180/2

=> 90
