Answer:
1/4, or 4 times smaller
Step-by-step explanation:
Since the surface area of a cube is just the combination of the area of all of the square sides, and the formula for those is s^2, if the side length was decreased by 1/2 then the surface area would decrease by (1/2)^2=1/4. Hope this helps!

First tutor = 30 x 10 = $300
Second tutor = 30 x 14 = $420
Total = 420 + 300 = $720
