Answer:
y = 14x
Step-by-step explanation:
Use the direct variation equation, y = kx
Plug in 7 as y and 0.5 as x, and solve for k:
y = kx
7 = k(0.5)
14 = k
Plug this into the equation:
So, the equation of variation is y = 14x
4/7
5/7 x (1/5+3/5) = 5/7 x 4/5 = 4/7
6 *20 = 120
8 *60 = 480
120 + 480 = 600 pounds total
