Answer:
55 days
Step-by-step explanation:
<u>Number of bags of dough is 192</u>
<u>You have to calculate the number of days.</u>
<em>After 10 days, 4 bags are divided into 4 more bags: 4 + 4 =8</em>
<em>After 20 days: 8 + 8 = 16 </em>
<em>After 30 days: 16 + 16 = 32</em>
<em>After 40 days: 32 + 32 = 64</em>
<em>After 50 days: 64 + 64 = 128</em>
After 55 days: 128 + 64 = 192 (5 days will be considered since it is doubled in 10 days and this time it is divided into half the amount)
Therefore, 55 days pass before 192 bags of dough are created.
