Answer:
<u>The additional 1.3% of increase in the annual interest rate that Jack is receiving in his savings account, from 2.8% to 4.1%, represent an increase of 46.42%.</u>
Step-by-step explanation:
Jacks's savings account annual interest rate before = 2.8%
Jacks's savings account annual interest rate after the increase = 4.1%
Difference of the two rates = 4.1% - 2.8% = 1.3%
How much percentage is that additional 1.3% from the rate before the increase?
(1.3 * 100)/ 2.8 = 130/2.8 = 46.42%
<u>The annual interest rate increased by 46.42% from the previous annual interest rate.</u>
In this item, we are informed that the order of the entries does not matter in determination the number of ways in which the Archie can choose for his party. Because the arrangement or order is not important, this type of problem uses the concept of COMBINATION.
The equation for combination is,
nCr = n!/((n - r)!(r!))
nCr is read as "combination of n taken r".
Substituting the known values to the equation,
15C6 = 15! / ((15 - 6)!(6!))
= 5005
Hence, there are 5005 ways in which Archee can choose the 6 entrees for his party.
Answer:

Step-by-step explanation:
The answer is the one above me
So we solve for 1 week and set them equal to each other
first job pay=second job pay
400=175+15%ofsales
x=number of sales
400=175+0.15x
solve for x
subtract 175 from both sides
225=0.15x
divide both sides by 0.15
1500=x
she has to earn $1500 in sales per week to have as much as the other job
