Answer:
Sam made it -24 versus 24 (29-5=24 not -24)
(Sam failed to flip the inequality)
Step-by-step explanation:
-4x + 5 > 29
Subtract 5 from each side
-4x+5-5 > 29-5
-4x > 24 Sam made it -24 versus 24 (29-5=24 not -24)
Divide by -4 Remember to flip the inequality
-4x/-4 < 24/-4 (Sam failed to flip the inequality)
x < -6

Write an equation to present her daily earnings?
Let daily sales be represented by x and daily earnings be represented by y.
y is calculated as thus;
![y = Earnings + Commission * Sales](https://tex.z-dn.net/?f=y%20%3D%20Earnings%20%2B%20Commission%20%2A%20Sales)
![y = 30 + 2\% * x](https://tex.z-dn.net/?f=y%20%3D%2030%20%2B%202%5C%25%20%2A%20x)
Convert percentage to decimal
![y = 30 + 0.02 * x](https://tex.z-dn.net/?f=y%20%3D%2030%20%2B%200.02%20%2A%20x)
![y = 30 + 0.02x](https://tex.z-dn.net/?f=y%20%3D%2030%20%2B%200.02x)
Hence, her daily earnings is ![y = 30 + 0.02x](https://tex.z-dn.net/?f=y%20%3D%2030%20%2B%200.02x)
