Answer:
6 seconds after it is launched
Step-by-step explanation:
h(t) = -4t² + 16t + 48
The balloon is at ground level when it lands.
When it is launched, t = 0, and h(0) = 48
When it lands, at time t, h(t) = 0.
-4t² + 16t + 48 = 0
t² - 4t - 12 = 0
(t - 6)(t + 2) = 0
t = 6 or t = -2
The balloon will hit the ground 6 seconds after it is launched.
First, since we're told there is a 29% discount on the original price, then $213 must be 71% of the original price because 100%-29%=71%. Then, it is also important to realize that we should use the decimal form of 71% which is 0.71. This is found by dividing 71 by 100 or simply moving the decimal point twice to the right. Then, we can write the equation 0.71x=213 where x represents the original price. This equation is essentially saying that 71% of some price is equal to $213. To solve this equation, you have to divide both sides by 0.71 to get x=$300 which is the final answer.
I hope this helps.
