Answer:D
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 8.5%/100 = 0.085 per year
putting time into years for simplicity
6 months ÷ 12 months/year = 0.5 years
then, solving our equation
I = 10000 × 0.085 × 0.5 = 425
I = $ 425.00
on a principal of $ 10,000.00
at a rate of 8.5% per year
for 0.5 years (6 months) is $ 425.00
Answer:
I love algebra anyways
the ans is in the picture with the steps
(hope it helps can i plz have brainlist :D hehe)
Step-by-step explanation:
0.50x-6=4
move -6 to the other side
sign changes from -6 to 6
0.50x-6+6= 4+6
0.50x= 10
divide by 0.50 for both sides
0.50/0.50x= 10/0.50
x= 20
Answer: x= 20
The problem is asking how much each person will need to pay. Simplifying the problem into an equation with variables (an algorithm) will greatly help you solve it:
S = Sales Tax = $ 7.18 per any purchase
A = Admission Ticket = $ 22.50 entry price for one person (no tax applied)
F = Food = $ 35.50 purchases for two people
We know the cost for one person was: (22.50) + [(35.50/2) + 7.18] =
$ 47.43 per person. Now we can check each method and see which one is the correct algorithm:
Method A)
[2A + (F + 2S)] / 2 = [ (2)(22.50) + [35.50 + (2)(7.18)] ]/ 2 = $47.43
Method A is the correct answer
Method B)
[(2A + (1/2)F + 2S) /2 = [(2)(22.50) + 35.50(1/2) + (2)7.18] / 2 = $38.55
Wrong answer. This method is incorrect because the tax for both tickets bought are not being used in the equation.
Method C)
[(A + F) / 2 ]+ S = [(22.50 + 35.50) / 2 ] + 7.18 = $35.93
Wrong answer. Incorrect Method. The food cost is being reduced to the cost of one person but admission price is set for two people.
Answer:It should be x=1 not sure thought.
