3x + 15/6 =2x - 5
(6/1)(3x + 15/6) = (2x-5)(6)
3x + 15 = 12x - 30
-9x = -45
x = 5
Simple, finding markup, you'll use two equations
Markup=New-Original
Markup%=Markup/Original*100
Markup=31-20
Markup=11
Then,
Markup%= 11/20*100
M%=0.55*100
M%=55%
Thus, the percent of change was, 55%.

False
Step-by-step explanation:
The included side in ASA is inside between the angles being used
The ratio of $2 to $5 is 3: 1
3x$2 + 1x$5 = $11
A set of 3 $2 and 1 $5 gives you $11.
Assumed all 160 coins are $1
Total value = $100
Difference in the value = $300 - $100 = $200
Difference in the $1 and the set of $2 and $5 = $11 - $1 = $10
Number of set of $2 and $5 = $200 ÷ $10 = 20
Calculate the number of $2 and $5 in the 20 sets:
Number of $2 = 3 x 20 = 60
Number of $5 = 1 x 20 = 20
Number of $1 = 160 - 60 - 20 = 80
Answer: There are 80 $1, 60 $2 and 20 $5.
