31 x 10= 310

14 x 5= 210

4 x 2= 8

62 x 1= 1

and that was the bills, add them together, you get 529.

then multiply the amount of what the change is by the amount of change there is so, 13 x 25= 325 3 x 5= 15 and 93 x 1= 93.

add the change

325+15+93= 433

add the amount of how much each totals were worth:

433+592 = $1025

Consider a refrigerator that consumes 320 W of elec- tric power when it is running. If the refrigerator runs only one quarter of

irinina [24]

Answer: The refrigerator cost in this month is $4.5 approximately.

Step-by-step explanation:

Since we have given that

Amount of watt of electric power = 320 W

Number of days = 30

Unit cost of electricity = $0.13/Kwh

Hold factor = $\dfrac{1}{4}$

Number of hours in a month = 24

So, the refrigerator cost in this month would be

$0.13\times 0.32\times \dfrac{1}{4}\times 30\times 24\\\\=\$7.488$

Hence, the refrigerator cost in this month is $4.5 approximately.
