2 meters were used in 10 masks
2meters/10masks= 0.2meters per mask
Answer: The trip was 440 miles
Step-by-step explanation:
A girl scout leader rented a bus for a trip to the museum.
Let x represent the number of miles
traveled over 350 miles.
Let y represent the total cost of travelling x miles
The bus company charged $275 plus $.35 for each mile traveled over 350 miles. This means that for x miles, the cost will be
y = 275 + 0.35x
If the bus trip cost $429, it means that y = 429
To determine the number of miles,we will substitute y = 429 into the equation. It becomes
429 = 275 + 0.35x
0.35x = 429 - 275 = 154
x = 154/0.35 = 440
x = 440 miles
Answer:
5x-5
Step-by-step explanation:
Answer:
The sales tax in one state is 5%. Write a function rule for finding the total cost of an item with selling price x. Then find the total cost of a CD player with a selling price of $110.
A. f(x) = 5 + x; $111.05
B. f(x) = 0.05x; $5.50
C. f(x) = x � 5; $108.95
D. f(x) =1.05x; $115.50
total cost = (price) + (5% of price)
f(x) = x + 0.05x
f(x) = 1.05x
So the function is f(x) = 1.05x
Plug in x = 110 to get
f(x) = 1.05x
f(110) = 1.05*110
f(110) = 115.50
The item costs $115.50 (after tax is added on)
Step-by-step explanation:
1: the total cost of a CD player would be 104.76
2: Total Cost = (price) + (5% of price)
f(x) = x + 0.05x
f(x) = 1.05x
So the function is f(x) = 1.05x
Plug in x = 110 into the function
f(110) = 1.05*110
f(110) = 115.50
The item costs $115.50
3: Answer:
f(x) = .05x; $5.50
Step-by-step explanation:
f(x) = .05x
f(110) = .05(110) = $5.50
