Jada and Zeke compare their monthly text message plans. Jada's plan costs [tex]\$5[/tex] plus an additional [tex]\$0.05[/tex] per text. Zeke's plan costs [tex]\$0.10[/tex] per text. The equations below show the cost, [tex]c[/tex], for each plan depending on how many texts, [tex]t[/tex], are sent.

Jada's Plan: [tex]c = 0.05t + 5[/tex]

Zeke's Plan: [tex]c = 0.10t[/tex]

In one month, Jada and Zeke paid the same amount.

Enter the number of text messages they each sent.

Answer :

To determine how many text messages were sent, we equate the costs of the two plans.

Jada's plan is given by:
[tex]$$
c = 0.05t + 5,
$$[/tex]
and Zeke's plan is given by:
[tex]$$
c = 0.10t.
$$[/tex]

Since the costs are the same, we set the two equations equal to each other:
[tex]$$
0.05t + 5 = 0.10t.
$$[/tex]

Next, subtract [tex]$0.05t$[/tex] from both sides to get the terms involving [tex]$t$[/tex] on one side:
[tex]$$
5 = 0.10t - 0.05t.
$$[/tex]

Simplify the right-hand side:
[tex]$$
5 = 0.05t.
$$[/tex]

Now, solve for [tex]$t$[/tex] by dividing both sides by [tex]$0.05$[/tex]:
[tex]$$
t = \frac{5}{0.05}.
$$[/tex]

Calculating the division gives:
[tex]$$
t = 100.
$$[/tex]

Thus, Jada and Zeke each sent [tex]$100$[/tex] text messages in that month.
