Hello!
To write this equation we will use c to represent the total cost, and g to represent however many games you download.
c=12.49+0.99g
The constant rate is 12.49, that will never increase or change in our equation.
Depending on how many games you download, that will be the rate that affects our total cost.
If you only purchase one game, you only spend $13.48. Where as if you buy 10 games, you spend $22.39.
Answer:
-0.5x² + 20x + 100
Step-by-step explanation:
Given:
R = 25x - 0.5x²
C = 100 + 5x
P = R - C
Where,
P = profits
R = Revenue
C = Cost
which expression represents her profit in dollars?
P = R - C
R = 25x - 0.5x²
C = 100 + 5x
= 25x - 0.5x² -(-100 + 5x )
= 25x - 0.5x² + 100 - 5x
= -0.5x² + 20x + 100
The expression which represents her profit in dollars is -0.5x² + 20x + 100
Answer:
15 years
Step-by-step explanation:
Given data
P=$1,000
R=8%
A= $2200
I= A-P
I=2200-1000
I=$1200
Applying the formula
I=PRT/100
1200=1000*8*T/100
cross multiply
1200*100= 8000T
120000= 8000T
divide both sides by 8000
T=120000/8000
T=15 years
Hence the time is 15 years
Answer:
3
Step-by-step explanation:
Yes it has the same value
They are exponents so it would be 8 times (4*4) + (2*2*2*2)
The exponent is how many times u multiple itself
