Well, 50 x 4 = 200, so just keep adding 0's!
50 x 4= 200
50 x 40 = 2,000
50 x 400 = 20,000
500 x 400 = 200,000

Answer:
9
Step-by-step explanation:
Ok... So there are 12 donuts in a dozen. And if she bought 3 dozen, she will have 36 donuts. If she plans to share them with her 3 friends, there will be 4 people total sharing the donuts. Then all you have to do is divide the 36 donuts among the 4 friends. 36/4=9. So they will all get 9 donuts.
3(12)/4=x
36/4=x
9=x
<u>x=9</u>
Hello There!
<u><em>n - d = 0</em></u>
<u><em>5n+10d = 90</em></u>
<u><em>----------------------</em></u>
<u><em>n-d = 0</em></u>
<u><em>n+2d = 18</em></u>
<u><em>-------------------</em></u>
<u><em>Subtract and solve for "d":</em></u>
<u><em>3d = 18</em></u>
<u><em>d = 6 (# of dimes)</em></u>
<u><em>n = d = 6 (# of nickels)</em></u>
Answer:
$7.99
Step-by-step explanation:
7.4*0.08 = 0.592 (0.59)
7.4 + 0.59 = 7.99
Invested at 7%: s
Invested at 5.5%: f
Then s+f=$15000, or f= $15000-s
Then add together the 2 interest amounts:
i = s(0.07) at 7%
i = f(0.055) at 5.5%
Then 0.07s + (15000-s)(0.055) = $952.50
Solve this for s, the amt. invested at 7%:
0.07s + 15000(0.055) - 0.055s = 952.50
Combining the s terms,
0.015s = 952.50-825
952.50-825
Then s = ------------------- = 8500
0.015
Ruth invests $8500 at 7% and $6500 at 5.5%.
