-7y-4x=17y-2x=53
-4x=24y-2x=53
-2x=24y=53
24y+2x=53
You would have to solve one at a time.
y=53/24
y=2.21
x=53/2
x=26.5
Given that loan amount P=20000
Interest rate r=5% = 0.05
Time of loan t=4 years
Now to find the interest amount we just plug those values into formula
simple interest = P × r × t
simple interest = 20000* 0.05* 4
simple interest = 1000 * 4
simple interest = 4000
Hence final answer is choice b. $4000.
Answer:
9
Step-by-step explanation:
I think what they are asking is to subtract the 3 tokens from 21 tokens he already has giving us 18. and since it says "Twice the number of tokens" I'm assuming you divide 2 from 18 giving you 9 tokens.
