Answer: 
Step-by-step explanation:
Given
Rate of painting 50¢ per square foot
Cost of paint is $100
If the total bill is $475
We can write,
![\Rightarrow 475=100+0.5\times x\quad [x=\text{area in square foot}]\\\Rightarrow 375=0.5x\\\Rightarrow x=750\ ft^2](https://tex.z-dn.net/?f=%5CRightarrow%20475%3D100%2B0.5%5Ctimes%20x%5Cquad%20%5Bx%3D%5Ctext%7Barea%20in%20square%20foot%7D%5D%5C%5C%5CRightarrow%20375%3D0.5x%5C%5C%5CRightarrow%20x%3D750%5C%20ft%5E2)
Thus, must be painted.

Answer: The mass of solid a is 4800 grams
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
For solid b = 40.32 cm2 / 6912 grams
For solid a = 28 cm2 / x grams
Where x is the mass of solid a.
So:
40.32 / 6912 = 28 / x
x = 28 / (40.32 / 6912)
x = 4800 grams
The mass of a is 4800 grams
