Answer:
Option 4: $2.18
Explanation:
Lets first analyse our given information. We know that:
- Original Cost Per Jug: $0.80
- Mark Up cost: 150%
- Sales Tax: 9%
Now the Mark Up cost essentially means that the original price of any item has gone up (i.e. increased). So first let us find the Mark Up final cost of a $0.80 jug when price has increased by 150%, as follow:
![0.80+0.80(150)/(100) =0.80 + 1.2=2](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xi89ah4hba9a2vc56yd0bae1i05ydk7un0.png)
Thus the jug after the mark up now costs $2.
Now lets compute the sales tax on the final jug cost, thus the 9% Tax on $2 as follow:
![2+2(9)/(100)=2+0.18=2.18](https://img.qammunity.org/2020/formulas/mathematics/middle-school/d2r24cqq1hxx61up206ywze5vyux0yw00g.png)
So finally the total cost of a jug of iced tea from A-1 Deli is $2.18 dollars (i.e. Option 4).
