So basically the answer would be 3 but it’s a little hard to explain. hope it helped
Answer:
k = 3
Step-by-step explanation:
Given that y and x are directly related then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 81 when x = 27
k = 
= 
= 3
145% of what number is 870 is 870/1.45=600
Answer=600
The formula for exponential growth is written as y = a(1 + RATE)^time
where a is the starting value, rate is the percentage of growth written as a decimal and time in this case would be the number of days.
You are given the growth rate as 11% and the starting day was day 1.
Since the table only goes to 10 days, you can use 10 as the time, or use X as an exponent if you need to calculate more than 10 days.
Using all this information, the formula becomes y = 1(1.11)^10 for 10 days or y = 1(1.11)^x for any number of days needed.
