Answer:
There are no possible solutions
Step-by-step explanation:
Given:
Minimum number of coins Alexa has =28 coins
Number of quarters Alexa has = 17 quarters
Total amount in coins = $5.05 = 505 cents
Let number of dimes be =
coins
So we can have two inequalities.
1) Total number of coins
[Since minimum number of coins=28]
2) Total value of coins
[As 1 dime=10 cents and 1 quarter=25 cents]

Solving inequality (1)
Subtracting both sides by 17.

∴ 
Solving inequality (2)
Subtracting both sides by 425.


Dividing both sides by 10.

∴ 
On combining both solutions
and
,
we see that there are no possible solutions as number of dimes cannot be ≥11 and ≤8 at the same time.
<span>Being able to express numbers in its equivalent forms allows you to give more accurate and correct answers. By using equivalents forms you may find a simply and easier way to solve the given equation.
For example, in fraction, by simply expressing equivalent fractions with common denominator, you can easily subtract and add the given numbers in an easy way. There are a lot of numbers that are equivalent, and there are a lot of way to solve a single problem to get a correct answer.</span>
