Q: Mandy’s phone data plan charges $30 per month for data. Her first month, she got a promotional rate of one-third the normal price. However, in the fourth month she went over her data limit and was charged an extra fee of $15. How much did Mandy pay in the first 6 months for data?
A: Mandy paid 1 / 3 * 30 = 30 / 3 = $10 for her first month of data. She paid 30 + 15 = $45 for her fourth month of data. Minus those two months, she had 6 - 2 = 4 months of regular charges. Thus, Mandy paid 4 * 30 + 10 + 45 = 120 + 55 = $175 for the first 6 months for data. The answer is 175.
