Trey is saving money for a new motorcycle. He has already saved $300 and plans to save $35 per week. This situation can be represented by the function f (x) = 300 + 35x, where x is the number of weeks. How much money has Trey saved after 10 weeks

Okay so since the question is asking how much Trey saved after 10 weeks, it should be,

function f (x) = 300 + 35 (10) because x is weeks and the question is asking 10 weeks

Solving:

300 + 350 = 650

So Trey saved 350 dollars more and he has total 650 dollars
