Money with Erin = 5x
Money with Faye = 2x
Money with Sachin = 7x

7x - 2x = 90
5x = 90
x = 90/5
x = 18
Money with Erin = 5*18 = 90

FORMULA:
Volume of pyramid = L × B × H/3
Height of pyramid = 3V/area of base(L × B)
ANSWER:
So, we have to just plug the respective value.
Height of given pyramid = √(22.1² - 14²)
- √(488.41 - 196)
- √292.41 = 17.1m
Now, Volume of given pyramid = 28 × 28 × 17.1/3
Answer:
$89.93
Step-by-step explanation:
Set up an equation:
Variable x = original price
40/100 = 35.97/x
Cross multiply
40 × x = 100 × 35.97
40x = 3597
Divide both sides by 40
x = 89.925
Round to the nearest cent:
5 rounds up so:
89.93
Check your work (use the original number instead of the rounded number to be more exact):
89.925 × 40%
Convert the percentage into a decimal to multiply:
89.925 × 0.40
35.97
Correct!
