this is the answer. hope this helps

Answer 2

Answer: 54%

Explanation:

Given: The cost of 1 pound of potato in a local grocery store last week= $4

The cost of 1 pound of potato in a local grocery store last week after 8 % tax= $4+8% of $4

`=4+0.08*4=4+0.32=\$4.32`

The cost of 1 pound of potato in a local grocery store next week= $6

The cost of 1 pound of potato in a local grocery store next week after 8 % tax= $6+8% of $6

`=6+0.08*6=6+0.48=\$6.48`

The percentage increase in the cost of a pound of potatoes, including the sales tax will be given by :-

`P=\frac{\text{ increase in cost}}{\text{cost last week}}*100\\\\\Rioghtarrow\ P=(6.48-4.32)/(4)*100\\\\\Rightarrow\ P=(2.16)/(4)*100\\\\\Rightarrow\ P=54\%`
