Step-by-step explanation:
a=2
b=-7
c=-15
-(-7)+-sq root (-7)²-4(2)(-15) / 2(2)
7 +- sq root 169 / 4
7+- 13 / 4
7+13 / 4, 7-13 / 4
x=5 x=-3/2
Answer:
$50,112. Increase is $2,112
Step-by-step explanation:
1st way. $48,000 x 1.044 = $50,112. 1.044 is the same thing as saying 104.4% of the total price in decimal form, which is what the new price would be when adding 4.4% to the 100% of the original price. To get the amount of increase just find the difference in the two. $50,112-$48,000 = $2,112
2nd way. $48,000 x .044. = $2,112 .044 is 4.4% in decimal form. So you found the increase here. Add the increase to the original price. $48,000 + $2,112 to get the new price of $50,112.
