Problema Solution
A cell phone company charges a monthly fee of $10 for the first 1000 text messages and 10 cents for each additional text message. Miriam's bill for text message for the month of June is $38.50. How many text messages did she send that month?
Answer provided by our tutors
let x = the number of text messages that Miriam sent
and also we know that 10 cents = $0.1
10 + (x - 1000)*0.1 = 38.50
by solving we find
x = 1,285
