M varies directly as the square of N. If N increases by 10%, find the percentage change in M

Answer 1

m=k*n^2

m=k(n+.1)^2
m new= k*1.21 n^2
percent change: 21 percent

Answer 2

M = k N^2
m = k (1.10 N)^2

m = 1.21 k N^2 = 1.21 M
100 (m-M)/M = percent change = 21 %

Answer 3

M = k(n+1)²
M=k(1.01n)²
M= 1.21 kn² = 1.21m
100 = p. C
= 21%
