A hat and bell cost $1.10. The hat costs one dollar more than the bell. How much does the bell cost?

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

The right answer:              C =5 cts.

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 .. 

c)   cost of  bell5 Cents

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

it's very easy. The answer is a)10 cents

The right answer is option C5 Cents..... because hat cost one dollar more than bell cost. So if hat cost is1.05 and we defuct0.05 from hat cost.1.05 -0.05 =1$ bell cost is0.05

The answer is very simple. Art1.10 +1 Art =2.10 - bell1.10 =1dollar., so Art =1doller and bell=0.The answer is (d) None of the above.

$1 is for hat and10 Cents are for bell therefore1 +10 = $1.10
