Question #18039

Answer 1

assuming you mean adults not students

`2a+3c=$31`

Explanation:

Lets make adults=`a` and Children= `c`

There is `2` adults, so that is `2a`

And there is `3` children so that is `3c`

`2a+3c=`Total cost

Total cost `2 xx 8=$16` +`3 xx5=$15`

`$15+$16=$31`

`therefore` `2a+3c=$31`
