La tarifa y el cargo aparecen en la factura.

Because Spanish nouns normally use a definite article much more often than English.

• la tarifa = the fee/rate
• el cargo = the charge
• la factura = the bill/invoice

The articles must match the noun’s grammatical gender and number:

• tarifa is feminine singular → la
• cargo is masculine singular → el
• factura is feminine singular → la

Even when English might say something like Fee and charge appear on the bill, Spanish usually sounds more natural with the articles: La tarifa y el cargo aparecen en la factura.

Because the subject is plural: la tarifa y el cargo.

Two singular nouns joined by y normally make a plural subject, so the verb must also be plural.

• La tarifa aparece = The fee appears
• El cargo aparece = The charge appears
• La tarifa y el cargo aparecen = The fee and the charge appear

So aparecen is the third-person plural form of aparecer.

The infinitive is aparecer.

In this sentence, aparecen is:

• present tense
• third-person plural

Conjugation in the present:

• yo aparezco
• tú apareces
• él/ella/usted aparece
• nosotros/nosotras aparecemos
• vosotros/vosotras aparecéis
• ellos/ellas/ustedes aparecen

So here, aparecen means appear or show up.

They are related, but not exactly the same.

• tarifa often means a rate, fee, or set price
• cargo often means a charge, especially an added amount on a bill, account, or card

Depending on context:

• tarifa can be the standard cost for a service
• cargo can be the amount charged, or an extra charge

So in a billing context, the sentence suggests that both the fee/rate and the charge are listed on the invoice.

Because en is the natural preposition here for something that appears on/in a document.

• en la factura = on the bill / on the invoice

Spanish often uses en where English uses on with papers, screens, lists, and documents.

Examples:

• Está en la lista = It’s on the list
• Aparece en la pantalla = It appears on the screen
• Viene en la factura = It comes on the invoice

Using a would not fit this meaning, and sobre usually means about or physically on top of, so it would sound wrong here.

It can mean either, depending on context.

In much of Latin American Spanish, factura commonly refers to an invoice or bill, especially in commercial or service contexts.

Examples:

• Necesito la factura = I need the invoice
• La factura de electricidad = the electricity bill

So the best English translation depends on the situation, but both bill and invoice are possible.

Yes. In real usage, aparecer often means:

• to appear
• to show up
• to be shown
• to be listed

With documents, screens, reports, and bills, it often has the practical sense of being shown/listed there.

So La tarifa y el cargo aparecen en la factura could naturally be understood as:

• The fee and the charge appear on the bill.
• The fee and the charge are listed on the invoice.

A little, yes, but the original order is the most neutral.

Standard order:

• La tarifa y el cargo aparecen en la factura.

You could also say:

• En la factura aparecen la tarifa y el cargo.

This version emphasizes where they appear.

Both are grammatical, but the original is the most straightforward for a learner.

Because it is a Spanish word with Spanish pronunciation rules, even though it looks familiar to an English speaker.

In Spanish:

• c before a sounds like k
• g before o is a hard g
• stress falls naturally on CAR-go

Also, the meaning is different from the common English noun cargo meaning goods carried by a ship, truck, etc. In Spanish, cargo has several meanings, and in this sentence it means charge.

You usually should not do that here.

The most natural version is:

• La tarifa y el cargo aparecen en la factura.

Repeating the article helps clearly mark each noun. In Spanish, when two nouns are joined by y, it is very common to repeat the article if each noun is a separate item.

Leaving out el in la tarifa y el cargo would sound unnatural in this sentence.
