Question

Jaden has a prepaid phone plan (Plan A) that charges $0.15 for each text sent and $0.10 per minute for calls. If Jaden uses only text, write an equation for the cost, in dollars, of sending t texts.

a. C=0.15t
b. C=0.10t
c. C=0.15+0.10t
d. None of these

Answer 1

The equation for the cost, in dollars, of sending t texts is C = 0.15t.

Step-by-step explanation:

To write an equation for the cost, in dollars, of sending \( t \) texts under Plan A, we need to consider the price Jaden is charged per text and the number of texts sent. The problem states that Jaden is charged $0.15 for each text sent. Therefore, if Jaden sends one text, it will cost $0.15.

If Jaden sends two texts, it will cost $0.30, and so on. To generalize this for any number of texts \( t \), the cost \( C \) in dollars would be the price per text multiplied by the number of texts sent: \[ C = \text{Price per text} \times t \] Given the price per text is $0.15, we substitute this price into the equation: \[ C = 0.15 \times t \] So, the equation for calculating the cost of sending \( t \) texts is: \[ C = 0.15t \] Of the options given (a, b, c, and d), the correct equation is: a. \( C = 0.15t \)

The equation for the cost, in dollars, of sending t texts is C = 0.15t.
