Pete smith bought two new car tires from firestone for $89.95 per tire. firestone charged pete $3.25 per tire for mounting, $2.60 per tire for valves, and $3.80 per tire for balancing. what is pete's final bill?

First youll need to add all the numbers together to get the cost of one tire
89.95 + 3.25 + 2.60 + 3.80 = $99.60 
now that we know how much one tire costs, we can multiply the price of one tire by two to found out his final bill
99.60 x 2 = $199.20
Pete's final bill is $199.20 
let me know if you have any other questions
