Hey I'm in flvs too but I have a different teacher, what class and module is your DBA for?
Answer:
$70.47
Step-by-step explanation:
Since the cost of the aquarium with the 15% discount is $59.90 then $59.90 is 85% of the original price. Remember 100-15=785. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(85) = 59.90(100)
85x = 5990
x= $70.47
CINEMA A sells each movie pass for $5.50, and CINEMA B sells each movie pass for $5.60.
To find the cost of each pass in Cinema A, all you would have to do it divide 66 by 12, where you would get 5.5, which in other words would be $5.50. And to find the cost of each pass in Cinema B, you wound divide 28 by 5,and you would get 5.6, which is in other words, $5.60.
