| Total value |
0.4 u |
0.08 u + 0.64 |
0.32 u - 0.64 |
Amount of flour needed for muffins
= 0.08 x (1 u + 8)
= 0.08 u + 0.64
Amount of more flour for the swiss rows than the muffins
= 0.4 u - (0.08 u + 0.64)
= 0.4 u - 0.08 u - 0.64
= 0.32 u - 0.64
0.32 u - 0.64 = 1.92
0.32 u = 1.92 + 0.64
0.32 u = 2.56
1 u = 2.56 ÷ 0.32 = 8
Number of muffins baked
= 1 u + 8
= 8 + 8
= 16
Answer(s): 16
