Answer: Choice B
x+6y = 29 and x+3y = 24.5
==============================================
Step-by-step explanation:
x is the cost of a throw blanket
On top of this cost is the cost to embroider letters on it
Your name has 6 letters so it costs you an extra 6y dollars. Overall, you pay x+6y dollars. It says that your cost is $29
So that's where x+6y = 29 comes from.
-------------
Similarly, your friend also pays x dollars for the blanket itself plus an extra 3y dollars for the 3 letters in their name. Overall, they pay x+3y dollars. We're told they spent $24.50 which is where the equation x+3y = 24.5 comes from.
