18 x 16 = 2
16 - 2 = 14

35If Auntie Jen baked another 90 apple puffs, there would be equal number of vanilla puffs and apple puffs in the end.
35 u + 14 = 16 u + 90
35 u - 16 u = 90 - 14
19 u = 76
1 u = 76 ÷ 19 = 4
Total puffs that Auntie Jen baked
= 40 u + 16 + 40 u
= 80 u + 16
= 80 x 4 + 16
= 320 + 16
= 336
