K = 2G

K = 2G K-12 = 6(G-12)

K = 2G K-12 = 6(G-12)2G-12 = 6G - 72

K = 2G K-12 = 6(G-12)2G-12 = 6G - 72-12 = 4G - 72

K = 2G K-12 = 6(G-12)2G-12 = 6G - 72-12 = 4G - 7260 = 4G

K = 2G K-12 = 6(G-12)2G-12 = 6G - 72-12 = 4G - 7260 = 4GG=15

K = 2G K-12 = 6(G-12)2G-12 = 6G - 72-12 = 4G - 7260 = 4GG=15Kevin is 30

K = 2G K-12 = 6(G-12)2G-12 = 6G - 72-12 = 4G - 7260 = 4GG=15Kevin is 30Gabriella is 15
