The following quantities appear in the problem: Zeit \(t\) / Arbeit \(W\) / Energie \(E\) / Leistung \(P\) / Anzahl \(N\) / Preis \(p\) / Spezifischer Preis \(\hat p\) /
The following formulas must be used to solve the exercise: \(P = \dfrac{E}{t} = \dfrac{W}{t} = \dfrac{Q}{t} \quad \) \(p = N \cdot \hat p \quad \)

Exercise:
How many kWh of energy does a pqW toaster use in the morning if it is in operation for a total of pqmin? At a cost of pqcents/kWh estimate how much this would add to your monthly electric energy bill if you made toast four mornings per week.

Solution:
The toaster's energy conption in one morning is E Pt pq.kWpq.h pq.kWh. Four mornings per week for one month makes sixteen mornings. The energy conption for one month is therefore E' E pq.kWh. This will add pq.ct to your energy bill.
