Answer: Dealership 4: he would pay $40.33
Step-by-step explanation: I used a calculator, so if you have 1/3 you put 1 divided by 3 in your calculator and right that down somewhere completely
Then, you divide $121 dollars by the number you got for 1 divided by 3 and then multiply it by 121 and should get 40.3333333333 but you round to the nearest tenth so it would by 40.33
1÷3= 0.33333333333
121×0.33333333333= 40.3333333333
