anonymous · Answer

Adam goes to a skating rink on Tuesdays for $8.50. While there, he pays $1.50 for each item he buys at the concession stand. Which equation best represents this information?
		
y = 8.50x + 1.50
		
y = 8.50x - 1.50
		
y = 1.50x - 8.50
		
y = 1.50x + 8.50

y = 1,50x + 8.50

oops....y = 1.50x + 8.50

anonymous · Answer

why would it be y = 1.5x +8.5 though?

anonymous · Answer

The constant is how much he paid to get in, right? So that will be a 8.50.
How much does he spend more? 1.50 TIMES the number of items he buys which we can represent by x.

How much total does he spend?  1.5x+8.5
So y=1.5x+8.5

I see, thanks

1.50x --- the x is the number of items bought at the concession stand + 8.50 (the cost of admission) = y (total cost)
