Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Joseph has a refrigerator, a water heater in his house, and an electric oven that consumes power at different rates. The total amount of money that Joseph pays for the energy used by the refrigerator is three times the amount he pays for the power used by the water heater. If the electric oven uses power worth $500 in a month, twice what Joseph pays for the power the water heater uses, calculate the total amount he pays for the power used by these gadgets.

### Response:
 Ikiwa tanuri ya umeme hutumia umeme wenye thamani ya $500 kwa mwezi, mara mbili ya kiasi ambacho Joseph analipa kwa umeme unaotumiwa na boila maji, Joseph analipa $250 kwa umeme unaotumiwa na boila maji.
Jumla ya pesa ambayo Joseph analipa kwa umeme unaotumiwa na jokofu ni mara tatu ya kiasi ambacho analipa kwa umeme unaotumiwa na boila maji, jumla ya 3*$250=$<<3*250=750>>750
Kwa vifaa vyote vitatu, Joseph analipa $750+$250+$500 = $<<750+250+500=1500>>1500 kwa umeme unaotumiwa.
