Step-by-step explanation:

_________________________________

STEP (1)

We have to know how many pets does the pet store have.

Look : 10 + 9 + 8 = 27

So the pet store completely have 27 pets.

STEP (2)

Mario randomly selects a pet :

$\frac{10}{27} \\$

Is the Probability of selecting a cat.

##############################

$\frac{9}{27} \\$

Is the Probability of selecting a dog.

_________________________________

STEP (3)

(( or )) in mathematics means plus (( + )) .

So the Probability of selecting a cat or a dog means :

$\frac{10}{27} + \frac{9}{27} = \frac{19}{27} \\$

_________________________________

STEP (4)

There's no STEP 4.

And we're done.

Se obtuvo $ 280 de ganancia por la venta de bolillos.

Step-by-step explanation:

1) ¿Cuanta ganancia se obtuvo en la venta de donas?

La ganancia es el producto del porcentaje producido de donas, expresado como razón, el precio unitario de la dona y el total producido de panes. Es decir:

$C = \frac{40\,donas}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{dona} \right)$

$C = 448\,USD$

Se obtuvo $ 448 de ganancia por la venta de donas.

2) ¿Cuanta ganancia se obtuvo en la venta de bolillos?

La ganancia es el producto del porcentaje producido de bolillos, expresado como razón, el precio unitario del bolillo y el total producido de panes. Es decir:

$C = \frac{25\,bolillos}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{bolillo}\right)$

$C = 280\,USD$

Se obtuvo $ 280 de ganancia por la venta de bolillos.
