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.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
