Since in option B, the bacteria are growing exponentially, B would be the correct answer to this question.
Given that Dan borrowed $1,250.00 from his brother who is charging him 5% simple interest. Now we have to find the total payment that he needs to payback including interest. Hence we can use simple interest formula
I=PRT
Where P= 1250
R=5% =0.05
T=18 months = 18/12 = 1.5 years
Now plug these values into above formula
I=PRT=1250*0.05*1.5=93.75
So total payment including interest = 1250+93.75=1343.75
Hence final answer is $1343.75.
A = P + SI
A-P = SI
5425-5000 = 425
THEREFORE THE SIMPLE INTRESTE IS $425
SI = PTR/100
425 = 5000×1×R/100
425×100/5000×1=R
425×100÷5,000×1 = 8.5%
THEREFORE THE RATE IS 8.5%

Answer:
Step-by-step explanation:
Note that 80% is 8 times 10%.
Thus, we could start with "If 10% of a number is 7" and multiply both quantities by 8: "80% of a number is 56."
Think:
10% of a number is 7,
20% is 14,
50% is 35,
70% is 49, and
80% is 56.
