Answer: 7 over 24 I think so! Sorry I didn’t reduce
Step-by-step explanation:
Answer:
1st question: M=22.62 while C=75.38
2nd question: M=.22 while C=1.97
Step-by-step explanation:
If a mirror costing x dollars is marked up 30%, then we have to find x such that 30%x+x is 98 dollars.
We are solving:
.3x+x=98
Combine like terms:
1.3x=98
Divide both sides by 1.3:
x=75.38
M=98-75.38=22.62
C=75.38
So M=22.62 while C=75.38.
If ream of paper cost x and is marked up 11%, then we have to find x such that 11%x+x is 2.19.
We are solving:
.11x+x=2.19
1.11x=2.19
x=1 97
M=2.19-1.97=.22
So M=.22 while C=1.97
Answer:
$120.
Step-by-step explanation:
We have been given that Libby sold $60 worth of vegetables at the farmer's market.
Jess sold 3/4th of what Libby sold. Let us find 3/4 of 60.



Therefore, Jess sold $45 worth of vegetables.
We are told that Stephanie sold 1/3rd of what Jess sold. So let us 1/3rd of 45.


Therefore Stephanie sold $15 worth of vegetables.
Now let us add amounts of money earned by Libby, Jess and Stephanie to get the total money earned by all.


Therefore, they all sell $120 worth of vegetables together.
Grocery Store: Farmer's Market
Cost $2.80 $4.20
Weight 8 oz 14 oz
Unit Cost
Cost ÷ Weight $0.35 per oz $0.30 per oz
1 lb = 16 oz 16 oz 16 oz
Cost per pound
Unit Cost * 16oz $5.60 per lb $4.80 per lb
The blueberries in the farmer's market costs less than the blueberries from the grocery store.
One pound of blueberries from the farmer's market is cheaper by $0.80 than the blueberries from the grocery store. ($5.60 - $4.80 = $0.80)
Answer:
c) 44000 miles
Step-by-step explanation:
The regression line has the following format:

In which b is the slope(how much each mile costs) and a is the fixed number of miles flown.
In this problem, we have that:
. So

A person who spent $ 2000 is predicted to have flown:
This is y when x = 2000.


So the correct answer is:
c) 44000 miles
