Step-by-step explanation:
Multiply the cost of an item or service by the sales tax in order to find out the total cost.<span>Make sure you put the sales tax into decimal form. You do this by taking the percentage and sliding the decimal point two places to the left: ...<span>Example: $60 (item cost) x .075 (sales tax) = $4.5 total sales tax.</span></span>
30 - 5d - c + 3d
In this equation there are two numbers which have the letter d with them. These would be like terms.
You have -5d + 3d which equals -2d
The simplified form would be 30 -2d -c
