Answer:
Step-by-step explanation:
n + d = 12
0.05n + 0.1d = 1 ║ × ( - 10 )
n + d = 12 ..... <em>(1)</em>
- 0.5n - d = - 10 ..... <em>(2)</em>
<em>(1)</em> + <em>(2)</em>
0.5n = 2 ⇒ n = 4
d = 12 - 4 = 8
There are <em>4 nickels</em> and <em>8 dimes</em> in the pocket.

(16/4) x 3 = 4 x 3 = $12
Answer: The total cost of computer would be $719.95
Step-by-step explanation:
I use proportions for these types of problems so we begin with a proportion!
20/100=x/849
100x=16980
x=169.80
Then, after finding how much the discount is, we would subtract it.
849-169.80=679.20
Next, we would find the tax amount with another proportion to find what 6 percent of 679.20 is.
6/100=x/679.20
100x=4075.2
x=40.75
Lastly, we would add the tax, $40.75, plus the total after the discount, $679.20!
Hope this helps! Good luck! (:
