Answer:
$167,409.60 interest paid
Step-by-step explanation:
If $838.13 is paid each month for 25 years,
total paid = 848.13 x 12 x 25 = $254,439
Therefore, 254,439 - 120,000 = $134,439 interest paid
If $798.36 is paid each month for 30 years,
total paid = 798.36 x 12 x 30 = $287,409.60
Therefore, 287409.6 - 120,000 = $167,409.60 interest paid
First we need to write the equations for the given scenario. Using the equations, we can form a system of matrix for the situation.
Let the customer buys, x pounds of almonds, y pounds of cashews and z pounds of walnuts. Since he buys 12 pounds of mixed nuts, we can write:
Total cost of these mixed nuts was $118. So we can write:
Customer buys 2 more pounds of walnut than cashews. So, we can write:
Using these equations, we can set up the system of matrix as shown below in the image.
So, in the list of numbers, 8 and 9 are solutions
Answer: In first question answer is -28x+4
In second question required inequality is 3x+100 < 2x-250
Step-by-step explanation:
1. Since, here the given expression is 4(x+5)-8(2+4x)
= 4x+20-16-32x ( By distributive property)
=-28x +4 ( By operating like terms)
2. Here, let the number is x.
Then according to the given question, three times the number of candy is increased by 100
That is, 3x+100
And, 250 less than the two times of the candy
That is, 2x-250
And, 3x+100>2x-250
Which is the required expression.
Hence she should subtract 250 from 2x not 2x from 250.
