Y=x+10
y is the total cost
x is the number of toppings times $1
10 is the cost of the pizza
Multiply the original price by the percent of markup: 47x.045=2.115. Round: 2.115=2.12. Add original price and amount of markup: 47+2.12=49.12. Answer: $49.12 :)
(16*0) + (4*1)
16*10 = 160
4*1 = 4
160 + 4
The answer is 164! :)
