The simple interest I ( in dollars) for a savings account is jointly proportional to the product of the time t (in years) and th

In-s [12.5K]

Answer:

Part a) The constant of variation is $r=0.0567$ or $r=5.67\%$

Part b) $I=\$662.03$

Step-by-step explanation:

Part a) Find the constant of variation.

we know that

The simple interest formula is equal to

$I=P(rt)$

In this linear direct variation the constant r represent the constant of proportionality

where

I is the Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=5/12\ years\\ P=\$3,892\\ I=\$92\\r=?$

substitute the values and solve for r

$92=3,892(r(5/12))$

$r=(92*12)/(3,892*5)$

$r=0.0567$

Part b) what will the interest be after 3 years

in this part we have

$t=3\ years\\ P=\$3,892\\ I=?\\r=0.0567$

substitute the values

$I=3,892(0.0567*3)=\$662.03$

I dont know how to set it up. #20 solving equations with variables on both sides.

Gnoma [55]

First lets create an equation for each:

1) Cost = 5x + 60
2) Cost = 11x

Where x is the number of lessons.

Since we want to find the value of x (the number of lessons), we can set both equations equal to each other:

5x + 60 = 11x

Subtract 5x from both sides:

60 = 6x

Divide by 6:

x = 10
So it will take 10 lessons till a member and a nonmember pay the same amount.
