1 answer:
Answer:
The cost to buy 1 shirt and 2 ties is equal to $36.5
Step-by-step explanation:
Let
x-----> the cost of one shirt
y---> the cost of one tie
we know that
4x+2y=95 -----> equation A
3x+3y=84 -----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is the point (19.5,8.5)
see the attached figure
therefore
The cost of one shirt is $19.5
The cost of one tie is $8.5
The cost to buy 1 shirt and 2 ties is equal to
x+2y=19.5+2(8.5)=$36.5

The amount in the account at 12% interest is $3400 and the amount in the second account at 7% interest is $2600
Step-by-step explanation:

Second account :
We are given that At the end of the first year he had earned $590 in interest.
So,
So,the amount in the account at 12% interest is $3400
The amount in the second account at 7% interest =6000-x=6000-3400=2600
Hence the amount in the account at 12% interest is $3400 and the amount in the second account at 7% interest is $2600
