Question

Tim's phone service charges $26.81 plus an additional $0.23 for each text message sent per month. If Tim's phone bill was $32.56, which equation could be used to find how many text messages, x, Tim sent last month?

A. $26.81x - $0.23 = $32.56
B. $0.23x - $26.81 = $32.56
C. $26.81x + $0.23 = $32.56
D. $0.23x + $26.81 = $32.56

Answer 1

The equation that can be used to find the number of text messages, x, Tim sent last month is $0.23x + $26.81 = $32.56. After solving the equation, we find that Tim sent approximately 25 text messages last month.

Step-by-step explanation:

The equation that can be used to find the number of text messages, x, Tim sent last month is option D. $0.23x + $26.81 = $32.56.

To solve the equation, we need to isolate x.

First, subtract $26.81 from both sides of the equation:

$0.23x + $26.81 - $26.81 = $32.56 - $26.81

$0.23x = $5.75

Next, divide both sides of the equation by $0.23:

x = $5.75 / $0.23

x ≈ 25

Therefore, Tim sent approximately 25 text messages last month.
