<span>Barry’s
bagel emporium sells a dozen bagels for $5.00. This price is no longer
high enough to create a profit. The owner decides to raise the price. He
does not want to alarm his customers with too large of an increase. He
is considering four different plans.
</span>
<span>Plan B: Raise the price by 10 percent each week until the price reaches $8.00. - I'd say this plan is the correct one</span>
X = log (base b) y
The base of the log becomes the base of the exponent.
The x and y switch.
b^x = y
Answer:
The loan was for 9 months only
Step-by-step explanation:
In this question, we are concerned with calculating the time taken for a loan om an interest to be paid back
To calculate this, we use the simple interest formula
Mathematically;
I = PRT/100
where P is the principal which is the amount borrowed and that is $500 according to the question
R is the rate which is 8% according to the question
Interest can be calculated by subtracting the principal from the amount paid back = 530-500 = 30$
We now plug these values into the equation
30 = (500 × 8× T)/100
100 × 30 = 4000T
T = 3000/4000
T = 0.75 (same as 0.75 × 12 months = 9 months)
