How did you get $1800?

anonymous · Answer

Did you plug in 12 into f(x) to evaluate?

anonymous · Answer

ok im a little confused

anonymous · Answer

Well, the function you are given: f(x) gives you the total money saved after x number of weeks right?

anonymous · Answer

right

anonymous · Answer

Evaluate the expression: $$f(12) = $1000 + $150(12)$$

anonymous · Answer

f(12)=1300

anonymous · Answer

$$1000 + 150 \times 12 = 1000 + 1800 = 2800$$

anonymous · Answer

Please check your calculations.
