Answer: $6,000
Step-by-step explanation: If set up correctly, the value of the car at the end of 2006 times 0.6 (because the car is losing 0.4 of its value, so it keeps 0.6 of its value) should get you the value of the car at the end of 2007.
The equation should look like this:
(value of the car at the end of 2006) x 0.6 = (value of the car at the end of 2007)
Then you substitute: (value at the end of 2006) x 0.6 = 3600
Then divide: (value at the end of 2006) = 0.6 ÷ 3600
Then substitute again: (value at the end of 2006) = 6,000

y=3x+6
Step-by-step explanation:
point 1 (2;12)
point 2 (4;18)
m=3
y=mx+b
sub in a point and gradient
12=3(2)+b
12=6+b
b=6
y=3x+6
The last one is the answer
To answer this item, we let n be the number of scarves that Rebecca bought because the number is unknown. The total cost would be the sum of the amount paid for n scarves and 2 purses. The equation would then be,
5n + (12)(2) = 39
Simplifying,
5n + 24 = 39
Thus, the answer is letter B.
