Carli and Angela share a cell phone plan and split the bill each month. Last month, their total bill was $109. Carli went over her data limit on her phone, so her share of the bill was $15 more than Angela's to account for the overage charge. Which system of equations represents this situation?

A. c+a=15
c=a+109

B. c+a=109
c=a+15

C. c-a=15
c=a+109

D. c+a=109
a=c+15

Answer :

I think the answer is d because

The system of equations which represents the given situations are

[tex]c + a = 109[/tex]

[tex]c = 15 + a[/tex]

What is the system of equations?

A system of equations is a set of two or more equations with the same variables.

According to the given question.

Carli and Angela share a cell phone and split the bill each month.

Total amount on bill for last month = $109

Let the amount of money paid by Carli and Angela be c and a respectively.

so, the total amount paid by Carli and Angela is given by

[tex]c + a = 109[/tex]

Also, it is given that Carli pays $15 more than Angela.

⇒ [tex]c = 15 + a[/tex]

Therefore, the system of equations which represents the given situations are

[tex]c + a = 109[/tex]

[tex]c = 15 + a[/tex]

Thus, option B is correct.
