So, put your "x's" together first and then your intercepts. That should answer your question :)
Answer:
She is not breaking even. The discounted price is .84t, which is less than t.
Step-by-step explanation:
Retail price= 1.4
1.4×.4= .56
40% of 1.4 is .56
Subtract 40% of 1.4 from the retail price because she is marking down.
(1.4)-(.56)=.84
So the discounted price is .84t
This problem is difficult because we don't know if she sold any tea by the retail price and if she did how much did she sell.
Answer:
Step-by-step explanation:
Since you have
+
5
y
in one equation and
−
5
y
in the other equation, you can add both equations to cancel out the y terms and solve for x.
−

therefore
−
x
=

multiplying both sides by -1:
x
=
−
11
plugging this back into the first equation:
−

y
=

subtracting 66 from both sides:

y
=
−
65
divide both sides by 5:
y
=

13
putting the x-values and y-values into one point gives:
(

as the solution
Answer:
880 minutes
Step-by-step explanation:
cost = 0.05(per minute) + basic fee
y = 0.05x + 15
59 = 0.05x + 15
subtract 15
44 = 0.05x
divide by 0.05
x = 880
