Answer 1

Cost of movie ticket----- 1

Total cost of popcorn----- 15

Jonah's portion of popcorn cost------ 15/x

Explanation:

The cost of the Jonah's costs are represented by the expression :

11+15\x

Now we have to match the expression to the explanation that they denote.

Let x be the number of friends among whom the pop-corn cost has to splitted.

As the total cost of popcorn is: 15

Hence, Jonah's portion of pop-corn is: 15/x

Also, he bought a movie ticket for 11.

Hence, the total cost that is paid by Jonah is: 11+15/x

Answer 2

Let

x--------> the number of friends

y-------->Jonah's costs

we know that

`y=11+(15)/(x)`

where

The number of friends is ----------------------->
`x`

Cost of movie ticket is--------------------------->
`\$11`

Total cost of popcorn is------------------------->
`\$15`

Jonah's portion of popcorn cost------------>
`(\$15)/(x)`
