Answer:
180 dollars
Step-by-step explanation:
if it was discounted by 30 percent, that means 126 is 70 percent of the orin=inal price. If you divide 126 by 70, you get 1.8 is the money worth 1 percent. Multiply 1.8 by 100 to get the original price, and you end up with 180 dollars.
Let x be the number of pounds of beans that sells for $0.72 used and y
be the number of pounds of beans that sells for $0.52 used. Then:
x + y = 110 . . . (1)
0.72x + 0.52y = 81.4 . . . (2)
From (1), x = 110 - y . . . (3)
Putting (3) into (2) gives
0.72(110 - y) + 0.52y = 81.4
79.2 - 0.72y + 0.52y = 81.4
79.2 - 0.2y = 81.4
0.2y = 79.2 - 81.4 = -2.2
y = -2.2/0.2 = -11
x = 110 - (-11) = 110 + 11 = 121
The solution is not reasonable because, there cannot be negative value for the number of pounds of beans used.
And 121 pounds of beans cannot produce 110 pounds.
4,550 is the answer when you multiply the two numbers together.
Answer:
Please see the attachment for double number line.
Explanation:
We are given cost of 4 water bottles is $10
We can write ,
Cost of 4 bottles = $10
Cost of 1 bottle = $2.5
Cost of 2 bottles =$5
Cost of 3 bottles = = $7.5
Cost of n bottles = $2.5n
Now we draw the double number line.
Bottom line(Line 1) will take as number of bottles:
1 2 3 4 5 6
Above line (Line 2) will show the cost of corresponding number of bottles:
2.5 5 7.5 10 12.5 15
