Answer:

Variable y represent the rent of Pamela

Explanation:

Given

Pamela pays tuition every semester and rent every month, and she uses cash daily for food.

lets understand what constitute semester , month and day in a year.

A semester consist of 6 months.

As a year has 12 months , a year will have 2 semester.

If one pays x for one semester then in a year one has to pay 2x .

As a year has two semester

Similarly

A year has 12 months .

If one pays y for one month then in a year one has to pay 12y .

As a A year has 12 months .

A year has 365 days

If one pays z for each month then in a year one has to pay 365z .

As a A year has 365 days.

__________________________________________

Based on above discussion , we can now safely assume that the we have to look at the coefficient of expression 2x+12y+365z to find the which variable represent which type of bill.

As we have to find variable for rent and rent is paid monthly.

so for a year total bill will have 12 months and hence going by expression variable y represent the rent of Pamela.
