Answer:
A = 250(1 + 0.016)^0.75.
Step-by-step explanation:
9 months = 0.75 years
So A = 250(1 + 0.016)^0.75.
<span><span>1.
</span>James works as a waiter.
He served food with the following price
=> 23.59 dollars
=> 40.65 dollars
=> 30.50 dollars
=> 15.68 dollars
Let’s add this altogether:
=> 23.59 + 40.65 + 30.50 + 15.68
=> 110.42 the total of the ordered food.
Now, James received a tip of 17.67 dollars. Find the interest rate of his tip.
=> 110.42 * .50 = 55.21, thus the interest rate of tip is less than 50%
=> You can do trial and error to get the correct rate,
=> 110.42 * .16 = 17.67, thus he received 16% tip</span>
Answer:
A = 3
2A5A0A2 = 2353032
Step-by-step explanation:
Given:
2A5A0A2 is divisible by 9
2A5A0A2 can be divisible by 99 if the sum of the digits can be divided by 9
Digits A is between 0 to 9
2 + A + 5 + A + 0 + A + 2 = 9x
Where,
x = multiples of 9
9 + 3A = 9x
Make A the subject
A = (9x - 9) / 3
When x = 0
A = {9(0) - 9} / 3
= (0 - 9) /3
= -9/3
= -3
When x = 1
A = (9x - 9) / 3
= 9(1) - 9 /3
= 9-9/3
=0/3
A = 0
When x = 2
A = (9x - 9) / 3
= 9(2) -9 / 3
= 18-9/3
= 9/3
A = 3
When x = 3
A = (9x - 9) / 3
= 9(3) - 9 / 3
=27 - 9 /3
= 18/3
A = 6
When x = 4
A = (9x - 9) / 3
= 9(4) -9 /3
= 36-9/3
= 27/3
= 9
Recall, Digits A is between 0 to 9
Substituting A = 0
2050002 ÷ 99
= 20707.09
Substituting A = 3
2A5A0A2
2353032 ÷ 99
= 23,768
Substituting A = 6
2A5A0A2
2656062 ÷ 99
= 26,838.91
Substituting A = 9
2A5A0A2
2959092 ÷ 99
= 29,889.82
Therefore, the only A digit that will not give a decimal number when divided by 9 is 3
A = 3
