<u><em>Each answer is under each Part</em></u>
1. What is the price of you pizza with all the toppings?
<em><u>$16</u></em>
The pizza costs 12 dollars, and each topping costs 1.75 dollars, there are 4 toppings, so it's 12 + 1.75*4 = 12 + 4 = 16 dollars.
2. How much will you pay in tax?

It costs 16 dollars and tax is 5%, so 5% of 16. 16*5% = 16*0.05 = 0.8, so 0.8 dollars, or $0.80
3. What is the total cost including tax?
<u><em>$16.80</em></u>
Add the cost of the pizza with the tax, 16 + 0.8 = 16.8, $16.80
4. How much will each of you need to pay to cover the total price?
<u><em>$4.20</em></u>
There are 4 people total, You and 3 friends, so divide the total cost by 4, 16.80/4 = 4.2, so $4.20
