If the balance is grow linearly then it would take 34.9 months to reach $7000. If, on the other hand, the balance is growing 800(1+0.13)* where x represents the number of months, what would the b be after 34.9 months? Round your answer to the nearest cent. exponentially, f(x) 31550 f(x) = In order to solve this problem, we assume the balance is growing according to the exponential functi 800(1 + 0.13)*, where the variable x represents the total number of months. Here we are interested in knowing what the balance would be after 34.9 months, so substitute 34.9 for x. 315496 f(x) = 800(1.13)* f(34.9) = 800(1.13) 34.2 ≈ 56,954.45 So the balance after 34.9 months would be $56,954.45.
