Answer:
D
Step-by-step explanation:
We will let d represent the amount of dimes Angela has.
Angel has 5 fewer quarters than twice the number of dimes.
Twice the number of dimes will be 2d.
Then, 5 fewer will yield 2d-5.
Therefore, the amount of quarters Angela has is 2d-5.
Then, the total amount of coins (dimes and quarters) together, will be:

The first part is the amount of dimes.
And the second part is, as we determined, the amount of quarters.
Therefore, our answer is D.
Answer:
$2.72
Step-by-step explanation:
If the price decreased by 20%, the final price will be 100% - 20% = 80% of the inicial price.
So, we can write the ratio box:
Old value New value
Percent value: 100% 80%
Value: $3.40 X
Then we can solve with a rule of three:
100% -> $3.40
80% -> X
X = 0.8 * 3.4 = $2.72
The answer for this question is 2 and 3
