Answer:
$62.50
Step-by-step explanation:
The original price is x
It is marked up 40 percent
x+.40x = new price
1.40x = new price
The new price is 87.50
1.40x = 87.50
Divide each side by 1.40
1.40x/1.40 = 87.50/1.40
x =62.50
The price before mark up is 62.50
They should get 2 each cause 2 goes into 90 and 72 so 2 is your answer
The correct answer is 181 (rounded)
For the 2nd part of 2. just plug in what you have for G in your previous graph into the equation. This will give you H for all 5 columns . Like 3×8(-1+5)= h = 3× 32= 96 so H should equal 96 and so on as far as this function.
For number 3. The equation is given so just plug in your T for time which is 3 seconds, so...-16(3)^2+90(3) = H the height at 3 seconds. I'm doing it in my head but should be the height is 414. You should also say whether it's ft or inches etc because the teacher or yourself left that out of the equation which is also vital lol.
