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)
4 × 750 = 3 L so it will take 3 minutes for 4 canteens and
2 × 1.5 = 3 L it will also take 3 minutes
total it will take 6 minutes.
I believe the answer will be 100 because it’s close to a 90 degree angle
