Answer:
Savings = $13
Step-by-step explanation:
$0.12 = 1 kilowatt-hour
So,
For Top-Freezer Refridgerator:
$0.12 × 529 = 1 × 529 kilowatt-hour
$63.48 = 529 kilowatt-hour
For Side-by-Side Refridgerator:
$0.12 × 634 = 1 × 634 kilowatt-hour
$76.08 = 634 kilowatt-hour
Savings = Side-by-Side Refridgerator - Top-
Freezer Refridgerator
Savings = $( 76.08 -63.48 )
Savings = $12.6
Savings = $13
Given parameters;
Let us solve this problem step by step;
Let us represent Simon's money by S
Kande's money by K
- Simon has more money than Kande
S > K
- if Simon gave Kande K20, they would have the same amount;
if Simon gives $20, his money will be S - 20 lesser;
When Kande receives $20, his money will increase to K + 20
S - 20 = K + 20 ------ (i)
- While if Kande gave Simon $22, Simon would then have twice as much as Kande;
if Kande gave Simon $22, his money will be K - 22
Simon's money, S + 22;
S + 22 = 2(K - 22) ------ (ii)
Now we have set up two equations, let us solve;
S - 20 = K + 20 ---- i
S + 22 = 2(K - 22) ; S + 22 = 2K - 44 ---- ii
So, S - 20 = K + 20
S + 22 = 2K - 44
subtract both equations;
-20 - 22 = (k -2k) + 64
-42 = -k + 64
k = 106
Using equation i, let us find S;
S - 20 = K + 20
S - 20 = 106 + 20
S = 106 + 20 + 20 = 146
Therefore, Kande has $106 and Simon has $146
