Answer:

$1

Step-by-step explanation:

Let's call the ringtone r. If the ringtone and $3 equals $4, then we can write the equation $4=$3+r. To solve, all you have to do is isolate the r by subtracting 3 on each side.

Answer:

$1 is your answer!

Step-by-step explanation:

It is quite an obvious answer. ¯\_(ツ)_/¯

3+_= 4          OOOO This is 4 if you take away 3 you get:

4 - 3= 1          ффф О This is 4 - 3. You are left with 1

Now if one ringtone plus 3 dollars equals 4 then the ringtone was a dollar

1 + 3 = 4

1 Ringtone + $3 = $4

$1 + $3 = $4

So, your final answer is, the ringtone is $1.
