Answer:
100,000
Step-by-step explanation:
Investment ratio = 3 : 2
Rate = 5% and 4% simple interest
Total interest after 2 years = 9200
Let total investment = t
(3/5t * 0.05 * 2) + (2/5t * 0.04 * 2) = 9200
3/5t * 0.1 + 2/5t * 0.08 = 9200
0.06t + 0.032t = 9200
0.092t = 9200
t = 9200 / 0.092
t = 100,000
Answer:
Part 1) The number of minutes in a month must be greater than 50 in order for the plan A to be preferable
Part 2) The number of minutes in a month must be equal to 50 minutes
Step-by-step explanation:
<u><em>The question is</em></u>
Part 1) How many minutes would Kendra have to use in a month in order for the plan A to be preferable? Round your answer to the nearest minute
Part 2) Enter the number of minutes where Kendra will pay the same amount for each long distance phone plan
Part 1)
Let
x ---> the number of minutes
we have
<em>Cost Plan A</em>
<em>Cost Plan B</em>
we know that
In order for plan A to be cheaper than plan B, the following inequality must hold true.
cost of plan A < cost of plan B
substitute
solve for x
subtract 3x both sides
divide by 2 both sides
Rewrite
therefore
The number of minutes in a month must be greater than 50 in order for the plan A to be preferable
Part 2)
Let
x ---> the number of minutes
we have
<em>Cost Plan A</em>
<em>Cost Plan B</em>
we know that
In order for plan A cost the same than plan B, the following equation must hold true.
cost of plan A = cost of plan B
substitute
solve for x
therefore
The number of minutes in a month must be equal to 50 minutes
