The difference between the price that DeMarkus thought he should pay and the price that the store charged him is $24
The question provided is incomplete. Here is the complete question : DeMarkus says that a store overcharged him on the price of the video game he bought. He thought the price was marked 1/4 of the original price, but it was really 1/4 off the original price. He misread the advertisement. If the original price of the game was $48 , what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him? A. $28.50B. $36.00C. $42.50D. $24.00
The first step is to determine the price DeMarkus thought the price of the videogame was = 1/4 of the original price
1/4 x $48 = $12
The second step is to determine the actual discounted price.
Actual discounted price = original price = (1/4 of the price)
48 - (1/4 x $48 = $12)
$48 - $12 = $36
The third step is to determine the difference in the prices
$36 - $12 = $24

The correct answer is D). -15
Answer:
−2sin(2θ)cos(4θ)
Step-by-step explanation:
sin(2∅)-sin(6∅)
Sum product Identity
sinα - sinβ = 2cos((α+β)/2)sin((α-β)/2)
Putting α= 2∅ and β= 6∅ in the identity we get
sin(2∅)-sin(6∅) = 2cos((2∅+6∅)/2)sin((2∅-6∅)/2)
=2cos(8∅/2)sin(-4∅/2)
=2cos(4∅)sin(-2∅)
= -2sin(2∅)cos(4∅)
B)tan A=7/24. Because it’s the only correct ratio. Tan=opp/adj. Others are not the correct ratios so they can’t be used.
100 + 48=148 so that means she got 48 dollars for babysitting
