Question

verizon charges a flat fee of $35 for unlimited texts and data plus $0.28 for every local call made. if sarahs bill was $60.20, how many local calls did she make?

Explanation:

Step1: Subtract flat - fee from total cost

Let the number of local calls be $x$. First, find out the total cost just from local calls. Subtract the flat - fee from the total bill. The cost from local calls is $60.20 - 35=25.20$.

Step2: Calculate number of local calls

Since each local call costs $0.28$, we can find the number of calls $x$ by dividing the cost from local calls by the cost per call. So $x=\frac{25.20}{0.28}=90$.

Answer:

90
