Question

The table shows the total number of text messages that Ashley sent over 4 days. Write an equation to find the total number of messages sent in any number of days. Use the equation to find how many text messages Ashley would send in 30 days.

Answer 1

The equation is m = 25d

Ashley would send 750 text messages after 30 days.

Explanation:

The equation is y = mx + b

We see that each day the number of text increase by 25, so our equation is

m = 25d

Now we ask how many text messages Ashley would send in 30 days. We need to put 30 in for d and solve it.

m = 25(30)

m = 750 text messages

So, Ashley would send 750 text messages in 30 days.

Answer 2
