Ralph has budgeted $175 for entertainment. He uses this money to go out on dates for $35 or to go out with his friends for $15. Which budget line equation represents the situation?

A. 35x-15y=180

B. 35x+15y=180

C. (3x+5y) = 180

D. 180 - (35x+15y)

Assuming that Ralph budgeted $180 instead of $175 entertainment. He spent $35 per date and let "x" be the number of dates he attended. He spent $15 to go out with friends and let "y" the number of times that he go out with friends.

The correct expression is the "B" which is 35x + 15y = 180.
