Which equation can be used to determine p, the cost of b swim bags?
p = 7.50 + b
b = 7.50 + p
p = 7.50b
b = 7.50p

i think its either a or c
OpenStudy (michele_laino):
please, note that your equation is:
y=m*x. Now using your graph, we have to find m.
OpenStudy (michele_laino):
as I can see from your graph, I read that:
when x=2, y=15.
So I substitute x=2, and y=15, in the above equation, y=mx.

then I can write:
\[15=m*2\]
and dividing by 2, we have:
m=15/2.
OpenStudy (michele_laino):
So our equation is:
\[y=\frac{ 15 }{ 2 }x\]
OpenStudy (michele_laino):
or using your symbols:\[p=\frac{ 15 }{ 2 }b\]
OpenStudy (michele_laino):
so c., namely the third option
