Sharon counted the tires in groups of 2 which list shows numers she could have named? is it 12,14,16,18 or 8,12,16,21

Its the first group because they are all even

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
