Help me please, i don’t understand

Mathematics
1 answer:
DiKsa [7]3 years ago
3 0

Answer:

$9

Step-by-step explanation:

The linear system is going to be:

16m + 13s + 29c = $419

26m + 19s + 45c = $649

6m + 11s + 0c = $96

I don't really know why it is bringing up the determinant, all you need to do is put this into reduced row echelon form.  I personally used a calculator for this, but it could be done painstakingly by hand.

RREF gives me:

m=5

s=6

c=9

So a chocolate milkshake is $9

You want to put some money in a simple interest account it pays 8% interest annually for 2 years you would like to earn 500 doll
Semmy [17]

You deposit some money into a bank account paying 8% simple interest per year. You received $500 in interest after 2 years. How much the deposit (principal) was?


Result


The principal was $3125.


Explanation


Find principal by using the formula I=P⋅i⋅t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.


In this example I = $500, i = 8% and t = 2 years, so


IPPP=P⋅i⋅t=Ii⋅t=5000.08⋅2=3125
