In 1888, Thomas Adams was the first person to build a vending machine that dispensed chewing gum. The gum, named Tutti-Frutti, was available around New York City subway stations.
Answer:
a) Credit Balance R$1,000.00
Explanation:
The Duplicates Payable represents a Liability in Andorinha Ltd records.
When Andorinha Ltda paid a cash duplicate in the amount of R$500.000 the entries recorded will be :
Trade Payable-Duplicates R$500.000 (debit)
Cash R$500.000 (credit)
<em>Effect on Balance of Duplicates Payable</em>
Decrease in Duplicates Payable by $500,000
Remaining Balance is $100,000 (credit)
Okay so rewards and penalties make people make better decisions. So like if I don't get questions wrong on a test I receive $5 from my parents, but if I fail a test I'm grounded for a week. So I study more to get money. (this is not actually me just making an example). Rewards make people want to do better, and so do penalties. I don't want to do bad and get punished for it.
Solution:
Given Information,
Heat input is (
) = 5.5 ×
Btu/h
Combustion efficiency of the boiler (
) = 0.7
Combustion efficiency after turn up (
) = 0.8
Operation Hour (t) = 5200h
Unit cost (c) = 
Calculate heat output from the boiler
=
x 
= 5.5 x
x 0.7
= 3.85 x
Btu/h
Calculate the heat input to the boiler after the tune-up
=
/ 
= 3.85 x
/ 0.8
= 4.8125 x
Btu/h
Calculate the saved energy after the tune-up
=
- 
= 5.5 x
- 4.8125 x
Btu/h
= 0.6875 x
Btu/h
Calculate the annual energy saving (
)
=
x t
= ( 0.6875 x
Btu/h ) ( 5200 hr/yr)
= 3575 x
Btu/h
Calculate the annual cost saving
Annual cost saving =
x Unit cost
= 3575 x
Btu/h x 
= 82225
