Answer:
a)$4,238.50
b)$392
c)$3814.65
Step-by-step explanation:
a) 3920*0.08125=318.5
318.5+3920=4238.50
b)3920*0.1=392
c)3920-392=3528
3528*0.08125=286.65
3528+286.65=3814.65
Answer:
- 39 quarters and 41 nickels
Step-by-step explanation:
Let the number of quarters be x and nickels be y.
<u>Given:</u>
- Quarter is 25 cents
- Nickel is 5 cents
- Number of coins is 80
- Total amount is $11.80 = 1180 cents
<u>We have equations:</u>
- x + y = 80
- 25x + 5y = 1180
<u>Solve the system by elimination, subtract 5 times the first equation from the second one:</u>
- 25x + 5y - 5x - 5y = 1180 - 80*5
- 20x = 780
- x = 780/20
- x = 39
<u>Find the value of y:</u>
- 39 + y = 80
- y = 80 - 39y = 41
<u>Verify:</u>
- 25*39 + 5*41 = 975 + 205 = 1180
A is the answer. It has no repeating x points buy it repeats on the y coordinate, which is okay. The answer is A just to say it again.
Answer: A
Step-by-step explanation: with my calculation, and the information you have give i have to say it is A.
I think that you multiply 2 with 4 to get 8 and then multiply 8 with 7 to get that number then add 2.75... to get the total.
Hope it helped..
