7. A balloon with a small leak loses 10% of its volume each day. If it originally contained 24 liters of gas, what is the exponential function that represents this situation?
a. y=24(1+1)x
b. y = 24(1 +0.01)x
c. y = 24(1-1)x
d. y = 24(1 -0.01)x

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 2x^2 = 4x 2) 8 +2x = 2(4x) 3) 2 * 2 = 4 * 2 4) 4x^2 -2x = 0
