Answer:

Step-by-step explanation:
The given equation is:

so, we first isolate the exponential form that contains the unknown "z" in the exponent, by dividing both sides by 0.5:

Now we bring the exponent down by applying the natural log function on both sides, and then solve for "z":

45 minutes * 6 days = 270 minutes at the gum
but we need to change minutes to hours
1 hours = 60 minutes
270 minutes * 1 hr/60 minutes =
270/60 hours
divide top and bottom by 10
27/6
divide top and bottom by 3
9/2
4.5 hours
True , is the answer ! :)
