Answer: What is the question????
Answer:
t < ![\frac{38}{17}](https://tex.z-dn.net/?f=%5Cfrac%7B38%7D%7B17%7D)
Step-by-step explanation:
Add '5t' to both sides
12t - 2 +5t < -5t +36 +5t
17t -2 < 36
Add ' 2' to both sides
17t -2 +2 < 36 + 2
17t < 38
Dividing '17' on both sides
< ![\frac{38}{17}](https://tex.z-dn.net/?f=%5Cfrac%7B38%7D%7B17%7D)
Foil the right side. Multiply first, outer, inter, and the last terms. The right side is equal to x^2 + 11x + 18x. N is 11.
![x+y=500](https://tex.z-dn.net/?f=x%2By%3D500)
![0.05x+0.085y=40 ](https://tex.z-dn.net/?f=0.05x%2B0.085y%3D40%0A)
Multiply both sides of second equation by 20 to get
![x+1.7y=800](https://tex.z-dn.net/?f=x%2B1.7y%3D800)
Subtract that from first equation to get
![0.7y=300](https://tex.z-dn.net/?f=0.7y%3D300)
Divide both sides by 0.7 to get
![y=428.571](https://tex.z-dn.net/?f=y%3D428.571)
, so about $428.57 was spent in store. This leaves
![500-428.57=$71.43](https://tex.z-dn.net/?f=500-428.57%3D%2471.43)
that was spent online
