Answer:

The equation would help determine the cost 1 rubber stamps will be:

[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]

Step-by-step explanation:

Let x be the cost of 11 rubbers.

As the cost of 5 rubber stamps is $9.70.

Thus, the cost of 11 rubbers can be determined using the proportional ratios.

[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]

BONUS! let us solve to check

[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]

switch sides

[tex]\frac{x}{11}=\frac{9.7}{5}[/tex]

Multiply both sides by 11

[tex]\frac{11x}{11}=\frac{9.7\cdot \:11}{5}[/tex]

Simplify

[tex]x=21.34[/tex]

Thus, the cost of 11 rubber stamps: x = $21.34

Therefore, the equation would help determine the cost 1 rubber stamps will be:

[tex]\frac{9.7}{5}=\frac{x}{11}[/tex]

VERIFICIATION

Given

The cost of 5 rubber stamps = $9.70

Thus,

The cost of 1 rubber stamps = 9.70 / 5

                                               = $1.94

If the cost of 1 rubber stamp = $1.94

The cost of 11 rubber stamps = 11 × 1.94

                                                = $21.34
