Answer:

there are 59 nickels, 12 quarters, and 213 dimes

Explanation:

  • let n = nickels
  • let q = quarters
  • let d = dimes

first step:

d = 3 (n + q) = 3n + 3q

d + n + q = 284

0.10d + 0.05n + 0.25q = 27.25

second step:

3n + 3q + n + q = 284

0.10 (3n + 3q) + 0.5n + 0.25q = 27.25

third step:

4n + 4q = 284

0.3n + 0.3q + 0.05n + 0.25q = 27.25

fourth step:

n + q = 71

0.35n + 0.55q = 27.25

fifth step:

replace q = 71 - n

0.35n + 0.55(71 - n) = 27.25

sixth step:

0.35n + 39.05 - 0.55n = 27.25

seventh step:

11.8 = 0.2n

eighth step:

n = 59

q = 71 - 59 = 12

d = 284 - n - q = 284 - 59 - 12 = 213

The best contraceptive for them to use is condom.
The use of condom will protect them to some extent from all types of sexually transmitted diseases and the method does not have any side effect. The only disadvantage that is attached to it is that, the condom may break if not properly inserted or if it has expired.

quester [9]
For the answer to the question above,
we must use this formula,
(New - Old)/ (Ave. of New and Old)

In this case,
501k -500k/(500,500(which is the ave. of the two.
Then it would be 1k/500,500

Then the answer would be .0020
Then
-1.439.5/439.5 because this is the average of the two.
so the answer would be .0023

Then finally divide the rate on change of quantity by the rate of change in price which is
0.002/-0.0023

Then the answer would be -.87

So the elasticity on the demand of model T is .87 ( remove the negative because elasticity is always positive.)
