Answer:
<em>3n; 2 nickels and 6 quarters</em>
Step-by-step explanation:
"Peggy had three times as many quarters as nickels."
Whatever number of nickels she has, the number of quarters is 3 times as many.
Since she has n nickels, she has 3 times n quarters.
The number of quarters is 3n.
A nickel is worth $0.05, so n nickels are worth 0.05n.
A quarter is worth $0.25, so 3n quarters are worth 0.25(3n).
0.05n + 0.25(3n) = 1.60
0.05n + 0.75n = 1.6
0.8n = 1.6
n = 2
She has 2 nickels.
3n = 3(2) = 6
She has 6 quarters.

Answer:
<em>The original number is x = 66 .19</em>
Step-by-step explanation:
<em>Let 'x' be the number</em>
Given data a number is decreased by 19% the result is 66
x - 19% = 66
x-0.19 = 66
Adding '0.19' on both sides , we get
x - 0.19 +0.19 = 66 +0.19
x = 66 .19
<em>The original number is x = 66 .19</em>
