Answer:
D.165
Step-by-step explanation:
m varies directly with n
m = 120 when n = 8
given this we want to find m when n = 11
we can use the direct variation equation to do so
y = kx but instead of x and y values we have values of m and n
m = kn
the constant is k, we need to solve for it, we can do so by plugging in m = 120 and n = 8
120 = k(8)
solving for k
divide both sides by 8
k = 15
the constant of variation is 15
now we want to find m when n = 11
using the direct variation equation we acquire
m = 11(15)
multiply 11 and 15
m = 165
the answer is D
