Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Investment 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
substitute in the formula above and solve for t
We are given : In a furniture rental store a down payment = $100.
Monthly charge of the table = $72.50 per month.
Total amount to be paid for the table = $535.
Let us assume number of months be n for which Hilde rented the table.
We are given equation also 72.50n + 100 = 535.
We need to solve the equation for n.
72.50n + 100 = 535.
<em>Subtracting 100 from both sides, we get </em>
72.50n + 100-100 = 535-100
72.50n = 435
<em>Dividing both sides by 72.50, we get </em>
72.50n/72.50 = 435/72.50
n = 6.
<h3>Therefore, for 6 months Hilde rented the table.</h3>
