Answer:
$10.64
Step-by-step explanation:
The mark up is simply the difference between the cost of the good for the seller, and the final price that the customer pays.
In this case, the local grocer store purchased the food item for $5.75, and the markup is 85%, so we multiply 5.75 x 85% = 4.89, and this result is the value that will be increased to reach the final consumer price:
Final consumer price = 5.75 + 4.89 = $10.64
