10.78 is the answer.
19.6 x .55
Number of solutions: no roots
Type of solution: Not Real
Step-by-step explanation:
We need to identify the number of solutions and their types using the discriminant.
We are given: 
Rearranging:

Discriminant can be found by: 
where b=-40, a=10 and c=41
Putting values:

So, Discriminant is -40
If the discriminant is less than zero i.e -40 then there are no real roots.
So, Number of solutions: no roots
Type of solution: Not Real
Keywords: discriminant

A compound event, I believe
Usando proporciones, hay que Luis enviará 160 dólares a su familia.
<h3>¿Qué es una proporción?</h3>
Una proporción es una fracción de la cantidad total, y puede ser encontrada por intermedio de una regla de tres.
En este problema, la regla de tres es dada por:
15 dólares - 8 envíados
300 dólares - n envíados
Aplicando multiplicación cruzada:
15n = 300 x 8
n = (300 x 8)/15
n = 160
Luis enviará 160 dólares a su familia.
