i am edditing my post because i got the answer wrong
Answer:
25
Step-by-step explanation:
Once the negative value is taken away, it's the largest number out of the bunch.
I think that she could buy 3 tubes of paint because that's $25.50 and that gives you 28.50 for the canvas.
Find the GCF of 15 and 35
15=3*5
35=7*5
The Greatest Common Factor here is 5
Divide both the numerator and denominator by this value to get the simplest form.
15/5=3
35/5=7
Final answer: 3/7
