Nine years ago, tarah opened a savings account with her bank. she started with a balance of $359 and has not made any withdrawals or deposits since then. part a: if her interest rate is 8% each year, how much interest has accrued using simple interest?

617.48

Step-by-step explanation:

SI = P x R x T / 100

SI = Simple Interest

P = Principal

R = Rate

T = Time

SI = 359 x 9 x 8 / 100

=> SI = 2872 x 9 /100

=> SI = 25848 /100

=> SI = 258.48

New Balance = Principal + Simple Interest

=> New Balance = 359 + 258.48

=> New Balance = 617.48

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
