<h3>Y
ou have the correct answer</h3><h3>Interest rate = 21.5%</h3>
===============================================
Work Shown:
i = P*r*t .... simple interest formula
i = simple interest
i = 2075-1000 = 1075
P = 1000 = amount borrowed (principal)
r = unknown interest rate
t = 5 = time in years
So,
i = P*r*t
1075 = 1000*r*5
1075 = 5000r
5000r = 1075
r = 1075/5000
r = 0.215
r = 21.5%
Answer:
$6340
Step-by-step explanation:
First figure out what 6.5% of 4000 is by multiplying not dividing because dividing will give you a way bigger number.
4000 x 6.5%=260
260 x 9=2340
2340+4000=6340
Answer:
$1.25x > $35
x > 28
Step-by-step explanation:
An inequality is a type of equation where we use symbols such as greater than (>) and less than (<) to solve for a variable that can multiple answers. In this case, we are looking for the number of times a senior citizen must ride the bus in one month for the $35 monthly pass to be a better deal. So, the number of times the citizen rides times the cost of each bus ride must be greater than the cost of the montly pass:
$1.25x > $35, where 'x' represents the number of bus rides
If we solve for 'x' by dividing both sides by $1.25, than we know that x > 28, or that the senior citizen must ride the bus more than 28 times in the month for the monthly pass to be a better deal.
18 = 4 + 2n
18 - 4 = 2n
14 = 2n
n = 14/2
n = 7
