Their error is that they divided 12 by 30, instead of 30 by 12 in order to get the price per pair
the correct unit price is $2.50 per pair
2.5 * 12 = 30
X³ = 125/27
Cube root both sides to isolate the variable:
∛x³ = ∛(125/27)
x = ∛(125/27)
∛125 = 5, ∛27 = 3
x = 5/3
42/3 = 14
I think the unit rate is $14.
I hope this helps! :D
The answer to your question i think is b
Answer:
H= 121.25 meters
Step-by-step explanation:
To find the value of H after 30 months given the equation H=0.20x+115.25,
replace x by 30 in the equation and solve;
H=(0.20*30)+115.25
H=6+115.25
H= 121.25 meters
Therefore, the height will be 121.25 meters
