Mathematics for IGCSE & O level - Equations (Section 4 - No. 22)

Write an equation for the statement: The cost (C) of renting a car is a fixed charge (K) plus the number of days (d) multiplied by the daily rate (R).

C = K + dR

C = d + KR

C = K - dR

K = C + dR

Εξήγηση

The correct formula represents the total cost as the sum of the fixed charge and the variable cost (daily rate times the number of days).
