a) 10 Cents
b) 8 Cents
c) 5 Cents
d) None of the above
c>>>5 cent >>>>>>>>>>>>>>>>>>>>>>>>>>
C is the right option as
Hat is1$ more than bell that is what ever is the price of Bell +1$ = the price of Hat
Consider the following
if price of bell is0.10 than price of Hat is 0.10+1=1.10 not possible
if price of bell is0.01 than price of Hat is 0.01+1=1.01 not possible
so we have to take the half of0.10 that is0.05 now the equation is
if price of bell is0.05 than price of Hat is 0.05+1=1.05 total Hat1.05+ Bell0.05 =1.10
How?
first equation: h + b =1.10
second equation: h =1 + b
unknown variable: b = ?
Replacing:
(1+b) + b =1.10
1 +2b =1.10
2b =1.10 -1
2b =0.10
b =0.10/2
b =0.05 $ = 5 cents of US dollar
Its C5 cents meaning if the bell is for0.05 dollars then hat would be0.05+1 and adding1.05+0.05 gives the total cost i.e.1.1 USD
( C ) is the wright answer ..
cost of hat = one $ more than the price of bell =1.00 +0.05 = $1.05
together costs =1.05 +0.05=$1.10
The bell would cost10 cents and the hat would cost $1.
Let's solve.
Let H be the price of hat.
Let B be the price of bell.
Total Cost is $1.10
Hat is $1
Therefore
$1.10 = B + $1
B = $0.10
$1 is for hat and10 Cents are for bell therefore1 +10 = $1.10
