Answer:
Step-by-step explanation:
Jasmine is baking and selling cupcakes for $15 per dozen.
Let x be the number of dozens of cupcake made by Jasmine.
Her total sales= Sales Per Dozen X Number of Dozens of cupcake sold
= $15 X x = $15x
Since she would like to make more than $120 in cupcake sales.
It means her total sales must be greater than $120.
15x>120
x>120/15
x>8

The hourly growth rate of bacteria is 191.25
<u>Solution:</u>
Given that, initially Shelly put 85 bacteria and waits 4 hours
Amount of bacteria after 4 hours = 850
Now, number of bacteria increased = 850 bacteria – initial 85 bacteria
Number of increased bacteria = 850 – 85 = 765 bacteria.
So, 765 bacteria were produced in 4 hours.
So hourly growth rate( per hour) can be found out by as follows:
Hence, the hourly growth rate of bacteria is 191.25
