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":

Answer:
258 fruits.
Step-by-step explanation:
We have been given that one day at a supermarket, 258 fruits were sold in the morning, and 5/6 of the number of fruits sold in the morning were sold in the afternoon.

So the number of fruits sold in the next afternoon will be:




Therefore, 258 fruits were sold in the afternoon the next day.
