Answer:
The cost with sales tax would be $79.5
Step-by-step explanation:
We know that the total cost of an item including sales tax is given by the expression 1.06c where c is the cost of the item.
Now we're required to find the cost of the skateboard including sales tax, the skateboard has a cost of 75 dollars, therefore c = 75.
Total cost including sales tax = 1.06c = 1.06 (75) = 79.5.
Therefore, the cost of the skateboard including sales tax would be $79.5.
