#### Answer

sales tax = 16.10
total price = 246.10

#### Work Step by Step

sales tax = tax rate $\times$ purchase price
sales tax=7%$\times$(210 + 15 +5)
sales tax=7%$\times$(230)
sales tax=0.07$\times$(230) write 7% as 0.07
sales tax=16.1
total price = purchas price + sales tax=230 + 16.1 = 246.1
