| Total value |
0.6 u |
0.07 u + 0.42 |
0.53 u - 0.42 |
Amount of flour needed for muffins
= 0.07 x (1 u + 6)
= 0.07 u + 0.42
Amount of more flour for the strudels than the muffins
= 0.6 u - (0.07 u + 0.42)
= 0.6 u - 0.07 u - 0.42
= 0.53 u - 0.42
0.53 u - 0.42 = 2.23
0.53 u = 2.23 + 0.42
0.53 u = 2.65
1 u = 2.65 ÷ 0.53 = 5
Number of muffins baked
= 1 u + 6
= 5 + 6
= 11
Answer(s): 11
