Not enough information. The question doesn't say how much one quart of paint covers.
EDIT: here's the solution
we have to find the total area of the 4 walls and subtract the area of the door. there are 2 walls with dimensions 16 by 10, and 2 walls with dimensions 16 by 12. so we have: 2(16*10)+2(16*12)=320+384=704 for the area of the walls. now, we can find the area of the door which is 3*8=24. <span>so we subtract the area of the door from the area of the walls, so we have: 704-24=680. </span><span>Since a quart of paint covers 100, then we divide and get 680/100=6.8 but since we need a whole number of quarts, we round up to get 7 quarts of paint. </span>

We are given the statement:
She gets a base pay of $80 a day plus 5 percent of the
value of any merchandise she sells that exceeds a total of $400
Then we are given the equation:
Earnings = 400 + 0.05 (t – 80)
Now if we read the statement carefully, we can understand
that the base pay is $80 and NOT $400. Therefore it should be the constant
value in the equation. Now the statement also tells that what will be added to
her pay is anything beyond 400, therefore it should be the one inside the
parenthesis. That is:
<span>Earnings = 80 + 0.05 (t – 400) ---> correct equation</span>
Now we use the corrected equation to solve for the earnings
when t = 475
Earnings = 80 + 0.05 (475 – 400)
<span>Earnings = 83.75 dollars</span>
a) Wayne's savings before he spent $28 is $30
b) Stef's savings after she spent $28 is $8
<u>Step-by-step explanation</u>:
step 1 :
let,
Wayne's savings = 5x
Stef's savings = 6x
step 2 :
After spending $28 each of them, The ratio becomes 1/4.
⇒ (28 - 5x) / (28 - 6x) = 1/4
⇒ 4(28 - 5x) = 1 (28 - 6x)
⇒ 112 - 20x = 28 - 6x
⇒ 112 - 28 = 20x - 6x
⇒ 84 = 14 x
x = 84/4 = 6
step 3 :
a) Wayne's savings before he spent $28 = 5x
substitute x=6,
Wayne's savings = 5(6) = $30
step 4 :
b) Stef's savings after she spent $28 = Total savings - $28
= 6x - 28
= 6(6) - 28
∴ Stef's savings after she spent $28 = 36 - 28 =$8
