Answer:
$478.80
Step-by-step explanation:
38 people in total x 12.60
Set up a proportion
90/x = 60/100
60x = 9000
x = 150
if you're wondering why I used 60 instead of 40 in the proportion it is because $90 is 60% of the original price, not 40%
hope this helps!
Hi there!
We can find the answer by factoring the equation, then setting them up equal to zero.
x² - 7x + 12 = 0
(x - 3)(x - 4) = 0
x - 3 = 0 x - 4 = 0
x = 3 x = 4
So you have two real solutions for the equation x² - 7x + 12 = 0.
Hope this helped! :)
