Answer:
$6.34
Step-by-step explanation:
15.86 / 2.5 = 6.34
$6.34
Answer:
63.21%
Step-by-step explanation:
C=0.5x + 10
Where:
C = total cost of printing
x = number of business cards printed
0.5 = variable cost of printing, this cost depends on the number of business card
10 = fixed cost of printing, this cost stays the same regardless of the number of business card printed.
C = 0.5x + 10 ; derive the formula of x.
C - 10 = 0.5x
(C - 10)/0.5 = x
Answer:
yess
Step-by-step explanation:
Let x = miles traveled by car
Let y = miles traveled by truck.
Because the total distance is 305 miles,
x + y = 305 (1)
Let t = hours of travel by truck. Because the truck speed is 55 mph,
55*t = y
or
t = y/55 (2)
The car has an hour head start, therefore it travels for (t + 1) hours.
Because the car travels at 65 mph,
65*(t + 1) = x
Substitute (2) to obtain
65*(y/55 + 1) = x
or
1.1818y + 65 = x (3)
From (1), obtain
1.1818y + 65 = 305 - y
2.1818y = 240
y = 110
x = 305 - y = 195
From (2),
t = 110/55 = 2 hours
The two vehicles pass each other at 2:00 pm + 2 hours = 4:00 pm
Answer: 4:00 pm
