Question

What is the answer to this

Answer 1

Hi !
10 rubber stamps → $ 10.33
If 10 rubber stamps cost $ 6.55 , then you should find out how much it costs a rubber stamp,by dividing by 10 :  

 $\frac{10}{10}$ rubber stamps → $ $\frac{10.30}{10}$
1 rubber stamp → $ $\frac{10.30}{10}$

So, you have to multiply 1 marker by 2 :
2 rubber stamps →  2*\frac{10.30}{10} 

x - the cost of the 2 rubber stamps

⇒ x = 2*\frac{10.30}{10}   
    x = 2.06


A : x = 2*\frac{10}{10.30} =1.94 ≠ 2.06

B : x = 2*\frac{10}{10.30} =1.94 ≠ 2.06

C : x = 2*\frac{10}{10.30} =1.94 ≠ 2.06

D :  x = 2*\frac{10}{10.30} =1.94 ≠ 2.06


So,the answer is : E (none of the above)
