0.6 =
610 =
3514 x 20 = 5
20 - 5 = 15
If Auntie Rachel baked another 50 apple muffins, there would be equal number of cheese muffins and apple muffins in the end.
15 u + 15 = 8 u + 50
15 u - 8 u = 50 - 15
7 u = 35
1 u = 35 ÷ 7 = 5
Total muffins that Auntie Rachel baked
= 20 u + 20 + 20 u
= 40 u + 20
= 40 x 5 + 20
= 200 + 20
= 220
Answer(s): 220
