Answer :
Answer:
C(T) = $730 + $25T
R(T) = $35T
T = 193 transactions
Explanation:
Given that:
C = cost ; R = revenue ; T = number of transactions
Amount paid per transaction = $25
Cost keeping office open = $730
Amount collected on each transaction = $35
(a) Find a formula that gives C as a function of T.
C(T) = Cost of keeping office open + (cost per transaction × number of transactions)
C(T) = $730 + $25T
(b) Find a formula that gives R as a function of T.
R(T) = (Amount collected per transaction * number of transactions)
R(T) = $35T
(c) Find the number of daily transactions that are needed to make the revenue $1200 more than the cost.
R = C + 1200
Substitute the value of R and C into the equation:
35T = 730 + 25T + 1200
35T - 25T = 730 + 1200
10T = 1930
T = 1930 / 10
T = 193 transactions
