You buy a cellphone plan from T-Mobile and they charge you $50 for the phone and 0.50 cents per text message. Your best friend Sarah buys a cell phone plan from Verizon and she was charged $25 for the phone and $1.25 per text message.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
