Answer:
$68.00
Step-by-step explanation:
Let s represent the opening price. Then the closing price is ...
s - 3.25% × s = $65.79
s(1 -0.0325) = $65.79 . . . . collect terms
0.9675s = $65.79 . . . . . . . simplify
s = $65.79/0.9675 . . . . . . .divide by the coefficient of s
s = $68.00 . . . . . the opening stock price
Answer:
5 miles
Step-by-step explanation:
$12 = ($2 per mile) (2 people)
$12 = $2 + $2m (m = mile)
subtract 2 on both sides to eliminate
$12 - $2 = $2 - $2 + 2m
$10 = 2m
divide both sides by 2 to eleminate m
$10 / 2 = 2m / 2
m = 5

Answer:
Very little information is given, leaving room to multiple possible functions, however i would expect it to be y = 4x
Step-by-step explanation:
x * z = y
4 * z = 16
z = 16/4
z = 4
Answer:
Blue cars, B = 63 cars
Step-by-step explanation:
Let the blue cars be B.
Let the red cars be R.
Given the following data;
Ratio of B:R = 9:7 = 9 + 7 = 16
Red cars, R = 49
To find the number of blue cars;
First of all, we would determine the total number of cars using the expression;
R = 7/16 * x = 49
7x = 49 * 16
7x = 784
x = 112 cars
Now, we can find the number of blue cars;
B = 9/16 * 112
B = 1008/16
Blue cars, B = 63 cars
