reduction in bill after using new bulbs can be calculated by percent decrease in electricity using new bulb multiplied by last month Electricity bill from bulb use only.
framing in equation form we get;
reduction in bill after using new bulbs =
Now we will find this month electric bill for bulb use only.
this month electric bill for bulb use only can be calculated by subtracting reduction in bill after using new bulbs from last month electric bill for bulb use only.

Hence Kate's electric bill will be $9 for this month for bulb use only.
Answer:
The loaned amount at 11 % is $ 19,000
The loaned amount at 10 % is $ 2,500
Step-by-step explanation:
Given as :
The total loan amount = $21,500
The total interest earn = $2,340.00
The rate of interest are 11 % and 10 %
Let The loan amount at 11 % rate = $P
and The loan amount at 10 % rate = $21,500 - $P
Let The loan took for 1 year
Now,<u> From Simple Interest method </u>
Simple Interest =
=
Or, =
Similarly
=
∵ +
= $2,340
Or, +
= $2,340
Or, 11 P - 10 P + 215000 = 234000
Or, P = 234000 - 215000
∴ P = $ 19,000
And $21,500 - $ 19,000 = $ 2,500
Hence The loaned amount at 11 % is $ 19,000
And The loaned amount at 10 % is $ 2,500 Answer
