First you have to figure out how much a video game costs and how much a used one costs
Then you plug in the costs of the video games into Janets equation 120=3x+y
(x= video games and y=used video games)
Then you subtract the cost of video games from 120 and then divide that answer by the cost of used video games and that should give you how many used video games she can get
The final price is the cost plus the tax.
Since we know the tax and a percent, we can write this as
T = C(1+r)
T = what Graham paid = $87.45
C = cost before tax
r = tax rate expressed as a decimal = .40
Plugging in what we know
87.45 = C (1+.4)
87.45 = C(1.4)
Divide both sides by 1.4
C = $62.46
We have to find the area first
12 x 18=216 square feet
we do 216* $ 1.39= $ 300.24
Answer:
B) 12
Step-by-step explanation:
Opposite sides are congruent
Less than does mean minus, but when the question says less than some number, that number goes first. should have written 5-n
