Salma will run less than 35 miles this week. So far, she has run 18 miles. What are the possible numbers of additional miles she will run? Use t for the number of additional miles she will run.
Write your answer as an inequality solved for t.

We know that Salma will run less than 35 miles in total this week.

So if t represents the number of miles that Salma runs, we have the inequality:

0mi ≤ t < 35 mi

(where the first part comes because she can not run a number of negative miles, but this is trivial.)

We know that she already ran 18 miles, then we have now the inequality:

t + 18mi < 35mi

Now we need to isolate S

t < 35mi - 18mi

t < 17mi

So she can run any number of miles that is smaller than 17 miles.

For example, she could run 10 miles, 14 miles, 4.5 miles, etc.

one that is bigger than 3 1/2
