The function which represents the taxi fare in terms of distance d in meter is f(d) = 3.50 × + 40 .
 + 40 .
According to the question,
For first 500 meters cost is  40.00 and For each additional 300 meters cost is 3.50 .
Let, the total distance of taxi ride = d meters
Now, representing the equation of taxi fare in terms of distance when distance is less than 500
taxi fare = 3.50 ×   + 40
  + 40
∴  f(d) = 3.50 ×   + 40
 + 40

Answer:
shirt = $20
sweater = $35
Step-by-step explanation:
This question would be solved using simultaneous equation 
Let the price of sweater be represented by a
Let the price of shirt be represented by b
The following equations can be derived from the question 
2a + 4b = 150   equation 1 
4a + 3b = 200   equation 2 
Multiply equation 1 by 2 
4a + 8b = 300    equation 3 
Subtract equation 2 from 3 
5b = 100 
divide both sides of the equation by 5 
b = 20 
substitute for b in equation 1 
2a + 4(20) = 150 
2a + 80 = 150 
collect like terms
2a = 150 - 80 
2a = 70 
divide both sides by 2 
a = 35
Price of sweater = $35
Price of shirt = $20

I don't know if I'm right, but if each pencil is 10.5 grams then you multiply it by 5 ( number of pencils) and you get 52.5, which would not meet the standards of a pack weighing 60 to 95 grams.
