Answer:
C $320
Step-by-step explanation:
write equations for the two possible choices
situation 1:
y₁ = 20 + 0.5x, where y is the total price the club pays and x is the sales
** note i use 0.5 instead of 50, since 50 would represent 5000%
y₂ = 100 + 0.25x, where y is the total price the club pays and x is the sales
now set the two equations equal to each other
20 + 0.5x = 100 + 0.25x
isolate x by subtracting 0.25x and 20 from each side
20 + 0.5x - 0.25x - 20 = 100 + 0.25x -0.25x -20
0.25x = 80
divide both sides by 0.25
= 
x = 320
Answer:
1/6 mile
Step-by-step explanation:
Distance divided = 1/2 miles
No of sections = 3
Each division must equal = 1/2/3
= 1/2*1/3 = 1/6 mile.
The distance between each of the signs i.e between the first and second , second and third is 1/6 of the mile.
This can be done in decimals as well
1/2 mile= 0.5 mile.
When we divide 0.5 mile by 3 we get 0.167 which is equal to 1/6 in fractions.
Answer:
Options (1) and (2)
Step-by-step explanation:
Let the proportional relation between x and y is represented by,
y ∝ x
y = kx
Here, k = Proportionality constant
Option 1,
From the given table,
Graph of the points given in the table passes through origin.
For x = 0, y = 0.
For x = 1 and y = 9,
k = 
k = 9
For x = 2 and y = 18,
k = 
k = 9
Therefore, table represents a proportional relation.
Option 2.
From the given table,
Graph of the points given in the table passes through origin.
For x = 3 and y = 21,
k = 
k = 7
For x = 6 and y = 42,
k = 
k = 7
Therefore, table represents a proportional relation.
Option 3.
From the given table,
For x = 0, y = 1
But for the proportional relation graph should pass through origin (0, 0).
Therefore, table doesn't represent a proportional relation.
Option 4.
From the table given,
For x = 0, y = 2
Graph of the line doesn't pass through the origin (0, 0)
Therefore, table doesn't represent a proportional relation.
Options (1) and (2) are the correct options.
The solution is (3,2) cause both of the lines intersect at one point (which is a solution),and that point is (3,2) :)
The answer is letter D which is 90.5%. To come with the answer you need to add the cost of new computer which is $399 and the computer memory which is $42 with the total amount of $441. Then you $399 by $441 and multiple by 100%.
Solution:
= $399 + $42
= $441
=$399/$441 x 100%
=.9048 x 100%
= 90.48% or 90.50%
