Answer:
Step-by-step explanation:
$6/(2 DVDs) = $3/DVD, and $8/(4 CDs) = $2/CD
a DVD costs $3
a CD costs $2
Lynn bought 4 DVDs and 2 CDs for 4×$3 + 2×$2 = $16.
Pierre bought d DVDs and c CDs for $20.
d is 0, 2, 4, or 6
c = (20-3d)/2
(d,c) = (0,10), (2,7), (4,4), or (6,1)
For this case, we have the total of painters is 16, so to determine what percentage is painting the interior of the house, we make a rule of three:
16 ---------------> 100%
4 -----------------> x
Where "x" represents the% of painters who paint the interior of the house.

Thus, 25% of painters are painting the interior of the house.
Answer:
25%
