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.
It’s B) Research database
An equal number of eighth grade students chosen by chance from the athletic teams and school clubs
What you would first do is take each price and subtract it to get for the Shirt $14.04, The Tie would be $9.36, & the pants would be $27.30. Now add that all up to get $60.63 which would be the Selling Price!
Hope this helped :)
