1. is c

2. 5 years old

Step-by-step explanation:

1. it is c because we still do not know how old her sister is, or what the value of her sister is. so Britney is 7 years older than her sister who is X years old.

2. her sister is 5 years old because Britney is 7 years older than her. in this situation her sister is X years old, but they tell you what Britney's age is. so you do 12-7 because her sister is 7 years younger. 12-7= 5 so her sister is 5 years old. you can check this by doing 5+7, to get 12.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
