24 divided by 4 equals 6
Answer:
The total cost is $345
Step-by-step explanation:
Zoe purchased a barbecue grill originally priced at $600
Discount % = 50%
So, cost after discount = 
Cost after discount =300
Sales tax in Fairfax is 15%
So, cost including tax = 300+0.15(300)
Cost including tax = 345
Hence The total cost is $345
If she works 40 hours or less then she earns 20x dollars.
If she works more than 40 hours, then she earns 20×40 dollars for the first 40 hours and 30×(x-40) dollars for <span>every hour over 40 hours. The number of hours over 40 hours is x-40.</span>
Replace each of the x values given to see if they give 0.
0=(2/3)³+(2/3)²-1
0=(8/27)+(4/9)-1
0≠-0.259
0=(1)³+(1)²-1
0≠1
Therefore, you can see that the solution would have to be between 2/3 and 1.
Hope I helped :)
