Answer: D
Step-by-step explanation:
Answer:
y = 15x
Step-by-step explanation:
Given x and y are in direct variation then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 2, y = 30, then
30 = 2k ( divide both sides by 2 )
15 = k
y = 15x ← equation of variation
<h3>Answers:</h3><h3>First box = 57.14</h3><h3>Second box = 80</h3>
=============================================
Explanation:
If you save 65%, then you pay the remaining 35%
0.35x is the final price when x is the original price
0.35x = 20 solves to x = 57.14 approximately after dividing both sides by 0.35
57.14 goes in the first box
--------------
This must mean 80 goes in the other box.
Here's the steps on how to get 80
If you save 75% then you pay the remaining 25%
0.25x = 20
x = 20/0.25
x = 80
80 goes in the second box
