Answer:
$1.69
Step-by-step explanation:
Half a dollar = $0.50
Eight dimes = $0.80
Six nickels = $0.30
Nine pennies = $0.09
Total = $0.50 + $0.80 + $0.30 + $0.09 = $1.69
Use o fato de que o determinante de qualquer matriz quadrada é o mesmo da sua transposta.
30x - 20 = 50
use inverse operations to isolate x
30x - 20 = 50
+ 20 +20
30x = 70
(30x = 70) /30
x= 7/3 (this is the simplified term)
Equation:
626 = 230 + 230(x)
Solving equation for x:
626 = 230 + 230x
396 = 230x
x = 1.72
1.72 * 100 = 172%
The markup percentage is 172%.
Hope this helps!! :)
