Write the statement in symbols using the p and q given below. Then construct a truth table for the symbolic statement and select the best match.

p = I eat too much

q = I'll exercise.

I'll exercise if I eat too much.

Is it q->p?? I do not know how to do the truth table :(

I'll exercise if I eat too much.

can be rephrased as:

IF "I eat too much" THEN "I'll exercise"
≡ IF p THEN q.

Can you continue?

The truth table is a standard table for the conditional that you can find from any textbook or notes.

For p->q, it is false ONLY when p is true and q is false, the 3 other cases are all true.
