Answer:
Step-by-step explanation:
Let x be the distance driven, d-distance and C our constant.
Our information can be presented as:
#Subtracting equation 2 from 1:
Hence the fixed cost per mile driven,
is $0.20
To find the constant,
we substitute in any of the equations:
Now, substituting our values in the linear equation:
#y=cost of driving, x=distance driven
Hence the linear equation for the cost of driving is y+0.2x+284
Answer:
Option d.$18 to $30
Step-by-step explanation:
we know that
The quartet earn between $25 and $40 per hour.
so
If they play for 3 hours
then
($25*3)=$75
($40*3)=$120
the quartet will earn between $75 and $120
Divide the money equally between the four members
$75/4=$18.75
$120/4=$30
therefore
Each member can make between $18.75 and $30
Answer:
11/15

Step-by-step explanation:
Answer:
The original price of the shoes was $90.
Step-by-step explanation:
25% off means the price Joe paid for it is 75% of the original price.
Set up an equation:
75/100 = 67.50/x
Cross multiply
75 × x = 100 × 67.50
75x = 6750
x = 90
Check our work:
First solve for 25% off of 90 (our answer).
25% = 0.25
90 × 0.25 = 22.50
Next, subtract the discount from 90.
90 - 22.50 = 67.50
67.50 was what Joe paid so this is correct.
