Use the slope formula and slope intercept form to find this equation.
Y= 1/2x - 2
(I hope this is right :))
y=47.38+.617x
130 = 47.38+.617x
subtract 47.38 from each side
82.62=.617x
divide by .617 on each side
133.906 =x
to the nearest minute x=134
Answer Choice C
Answer:
y=^3Vx is the domain function
So here you are trying to find out what times .30 (30%) subtracted the original price will give you 18.75. Because it is 30% discount you want to use 70% (.7) so that you can find the price before not the price after.
so .7(x) = 18.75
Which you then divide and then get 26.79 dollars.
