For her cellular phone service, vera pays 32 a month + 0.75 for each minute over the allowed minutes in her plan vera received a bill for 47 last month for how many minutes did she use her phone beyond the allowed minutes

47 - 32 = 15

She paid 15$ more than she would have for her cellular phone service.
