Ineed in math that's one of the classes i'm okay but bad at.

a. C = 10.50 + 3.50n

b. $80.5

Step-by-step explanation:

A carnival costs $10.50 to enter plus an additional $3.50 per ticket for rides and food.

a. Let n represents the number of tickets purchased, then the algebraic expression to represent the total cost (C) to visit the carnival will be

C = 10.50 + 3.50n (1) (Answer)

b. If I purchase 20 tickets then the total cost to visit the fair will be given by equation (1) as

C = 10.50 + 3.50 × 20 = 80.5 dollars. (Answer)

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v

the 3rd on is correct
