Answer:
16
Step-by-step explanation:
x+y=30 solve for x x=30-y
substitute x with 30-y and solve
11.25x+22.4y=515.9
11.25(30-y)+22.4y=515.9
337.5+11.15y=515.9
11.15y=178.4
y=16
since we're solving for just large candles it's 16
if need small cangle number 30-16=14

Answer:Here are some more problems to solve.
Calculate the volume of a paperback book with the following dimensions:
Length = 12 cm
Width = 3 cm
Height = 20 cm
Calculate the volume of a steel bar with the following dimensions:
Length = 5 cm
Width = 2 cm
Height = 30 cm
Now determine the density of the steel bar if its mass is 2.34 kg. (Hint: Convert to grams first.)
A cork has a volume of 5.0 cm3 and a mass of 1.2 grams. Calculate its density.
Water has a density of 1 g/cm3. If you placed a cork and a steel paper clip in a jar of water, what do you think would happen? Use your knowledge of density to explain the outcome.
