Question

QUESTION 32 Suppose the amount of money in a bank account with an initial balance of $4,000 earns 1.3 percent interest per year. If the exponential function, y=A*B^x , is used to model this situation, which value would represent B in the function?

A 4,000
B 1.13
C 1.013
D 1.3

Answer 1

we know that initial balance is
`$4000` which is A.

and
`B` is the rate of interest.

where
`x` is the time period.

as we know that exponential relation, initial balance increase exponential with respect to time x.

`y=4000*1.3^x`

in place of B we have 1.3

so option D is the answer
