If not, you can multiply 3/4 by any fraction which has the same denominator and numerator. This will still be the same fraction, just with different numbers.

Look at the stem-and-leaf plot. How many numbers in the stem-and-leaf plot are greater than 110? A. 2 B. 8 C. 10 D. 11
Answers
Answer:
The answer is C.
Step-by-step explanation:
If you look at the Key 9/7 = 97 you see that the third row the first number is 112 which is greater than 110. After that all those numbers are greater than 110.
Total numbers given in the stem-and-leaf plot are 18, out of which 10 numbers are greater than 110.
Hence, Option (C) will be the correct option.
How to analyze a stem-and-leaf plot:Key of any stem-and-leaf plot is self explanatory.Example: A number 97 will be written as 9 | 7
So the numbers given in the stem-and-leaf plot are,
94, 97
100, 100, 100, 103, 106, 109
112, 112, 115, 118
121, 124, 127, 127
130, 132
Now we have to identify the numbers greater than 110.
So the numbers greater than 110 will be,
112, 112, 115, 118
121, 124, 127, 127
130, 132
Hence, total numbers greater than 110 are 10. Option (C) will be the correct option.

The bike store marks up the wholesale cost of all of the bikes they sell by 30%.
Andre wants to buy a bike that has a price tag of $125. What was the wholesale cost of this bike?
If the bike is discounted by 20%, how much will Andre pay (before tax)?
(Please make sure to add a good explanation on how you found the answer because I have seen some where I didn't understand where a certain number came from.)
Answers
Answer:
Wholesale: $37.50
Discount: $7.50
Explanation:
*The wholesale cost of all the bikes they sell is 30%
*Andre wants to buy a bike for $125
*If the bike is discounted by 20%
[tex]\frac{30}{100}[/tex] = [tex]\frac{x}{125}[/tex] (solve for x)
100x = 125 x 30
100x = 3750
(x = $37.50 for the wholesale)
For the discount, we need to find 20% of 37.5
An easier way we can do is to find 10% and to multiply by 2. So, move the decimal to the left of 37.5 and we get 3.75 and multiply by 2
3.75 x 2 = 7.5 ($7.50 the discount)

$37.50

Mr. Aamodt bought a new lawn tractor for $3,350.
a. The state sales tax on the lawn tractor purchase will be 6.5%. How much state sales tax will Mr. Aamodt pay on the tractor? (2 points)
b. Mr. Aamodt has applied for a 2‐year loan at the bank for $3,350 to pay for the new lawn tractor. The bank will charge him 8.4% simple interest on the loan. What amount of interest will Mr. Aamodt pay on the loan? (2 points)
c. What is the total cost of Mr. Aamodt’s new lawn tractor, including the purchase price, the loan interest, and the sales tax? (2 points)
Answers
Answer:
A) 217.75 sales tax
B)281.40 he will pay on the loan
C)$3849.15 he will pay including total cost, interest, and tax
Step-by-step explanation:
A)
To find sales tax, multiply the price by its percentage. 6.5% in decimal is 0.065. 3350x0.065=217.75 for its sales tax.
B)
This is the same for loan.
3350x0.084=281.40 he will pay for loan.
C)
Now add it all up. 3350+217.75+281.40=3849.15
Answer:
The correct answers are:
a. $217.75!
b. $281.40!
c. $3,849.15!
Step-by-step explanation:
a. Find the sales tax by multiplying the price by its percentage (6.5%, 0.065 in decimal form)
3,350 x 0.065=217.75
so the sales tax is $217.75
b. This is the same as finding tax. Find the loan by multiplying the original price by the percentage (8.4%, 0.084 in decimal form).
3,350 x 0.084 = 281.40
so the loan is $281.40
c. This time, sum the original price with both the loan and sales tax.
3,350 + 217.75+ 281.40= 3849.15
so the total cost for the new tractor is $3,849.15
So there you have it. You have your answers right here. Hope this helps! Be sure to mark this as brainliest!
