Mr. Dexter sells subscriptions to a magazine for $18 each. For each subscription he sells, he earns $8. One month, he sold $900 in subscriptions. How much did he earn?

Respuesta :

Answer:

  $400

Step-by-step explanation:

Dexter's earnings can be found using the proportion ...

  earnings/sales = $8/$18 = ??/$900

Multiplying by $900, we find ...

  ?? = $900(8/18) = $400

Dexter's earned $400 on the sales for the month.
