Danielle owes $29.50 for text messaging in the month of april. if her text messaging plan costs $15 for the first 350 messages and 0.25 for each additional text message, how many text messages did she send that month?

owes $29.50 in april

plan: $15 for 350 messages + $0.25 for each additional message

steps:

15 + 0.25x = 29.50  (let x = number of additional messages)

0.25x = 14.50 (subtract by 15 on both sides)

x = 58 (divide by 0.25)

58 + 350 = 408 messages

1. 3

2. 4

3. 1

hope this ! have a great day.
