Answer:
a) 92.30=26m+0.3t
b) 221 texts
Explanation:
If we plug in 1 for the month variable we get
92.30=26+0.3t
subtract 26 from both sides and we get 66.3=0.3t
Divide by 0.3 and we get t=221
Answer:
3 times
Explanation:
When the dough is folded, it increases by a constant factor. We can model the growth of the thickness using the exponential growth model

Where:
Initial thickness,
= 2mm
Growth factor, r =8%=0.08
We want to find the smallest number of times Soon Yi will have to roll and fold the dough so that the resulting dough is at least 2.5mm.
i.e When 

Therefore, the smallest number of times Soon Yi will have to roll and fold the dough so that the resulting dough is at least 2.5mm thick is 3.
