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 :
[tex] \frac{10}{10} [/tex] rubber stamps → $ [tex] \frac{10.30}{10} [/tex]
1 rubber stamp → $ [tex] \frac{10.30}{10} [/tex]
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)
