Answer:

The answer is the option B

[tex]0.50p+0.75e=3.50[/tex]

Step-by-step explanation:

Let

p------> the number of pencils

e------> the number of erasers

we know that

The total cost of pencils and erasers, is equal to the numbers of pencils multiplied by [tex]\$0.50[/tex] plus the number of erasers  multiplied by [tex]\$0.75[/tex]

so

[tex]0.50p+0.75e=3.50[/tex] ------> equation that represent the situation written in standard form
