danny makes p dollars an hour. he works q hours. his total weekly wage was $2.4. if he increases his hours, he will make an additional 15 cents per hour and make $3.3 total per week. What is the value of p?

This doesn't make sense to me. Did you include all the information as phrased in the problem?

increases hours and increases wage for additional weekly wage. You can solve the problem algebraically but there is no numerical solution. The weekly wages seem small... are you sure you copied the problem correctly?

From what you've given us it is something like...

q: original # of hours
p: original hourly wage
h: # of hours MORE than p

q * p = 2.40

(q + h) * (p + 0.15) = 3.30

2 equations, 3 unknowns... we need to know this "h" value I made up here.

I agree with the rest of the posters...
Two equations, three unknowns:
Set x=increased hours per week
(1) pq = 2.4
(2) (p+0.15)*(q+x)=3.3
