Ineed to know how to solve these simple interest word problems step by step. 1. what is the new balance of your account after 8 months if you earn 2.7% on your balance of $13,132? (by the way, i’ve tried .66 and .67 for time and it doesn’t give us our answer apparently : /) 2. last year you earned $273.47 in interest for your online savings account. if your starting balance was $8,546, what was your interest rate?

$236.38

3.20%

Step-by-step explanation:

Simple interest = PNR/100 where P = Principal = 13132/-

N = 8 months = 8/12 years and r = 2.7%

Hence simple interest = 13132 (8/12)(2.7/100)

= 236.376

= 236.38 dollars

2) On the same notation, here PNR/100 = 8546(1)(R)/100=273.47

Solving

R = 273.47(100)/8546 = 3.19999

= 3.20% apprxy.

step-by-step explanation:

try remembering the steps

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
