Han earned $850 over the summer working odd jobs. He wants to put his money into a savings account for when he is ready to buy a car. Han checks with another bank and their interest rate is 4%. How much longer will he have to leave his money in the account to earn the same amount of interest as the first bank? Answer in terms of months..

the line of

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
