So.. hmm notice the picture below
r = h, due to similar triangles ratio, whatever "h" may be
now, we're given how much water is being poured into the cup per sec
namely dv/dt the volume's rate
so.. hmmm
Answer:
Burger meal costs $8 and hot dog meal costs $6.
Step-by-step explanation:
To find the price per meal, write a system of equations.
Let b = cost of a burger meal and d = cost of a hot dog meal.
Write the equation 3b + 4d = 48 for the Woodsons.
Write the equation 6b + 2d = 60 for the Barkers.
Use elimination to solve the system. Begin by making the coefficients of one variable the same in both equations by multiplying 3b + 4d = 48 by 2.
2(3b + 4d = 48) ----> 6b + 8d = 96
Stack the equations and subtract.
6b + 8d = 96
- 6b + 2d = 60
------------------------
6d = 36
d = 6
Substitute d = 6 into one equation to solve for b.
3b + 4(6) = 48
3b + 24 = 48
3b = 24
b = 8
