Respuesta :

it is going to be option (3)

Answer: 3

This is because you multiply like terms. Since the half hour earnings should be multiplied with the half hour class amount, you will get how much money she will make. If you multiply it all together, you should get $180.

10x10 + 5x16

100 + 80

$180 (make sure you label your answer)
