The system of equations that can be used to determine the number of tetra fish and goldfish purchased is:
x = 2 y. 2 x + 1.5 y = 20
<h3>What are the system of equations ?</h3>
In order to determine the required values, two linear equations would be formed from the question. The two equations would exhibit the relationship between the two types of fishes:
The first equation would show the ratio between the two types of fishes bought: 2y = x
Th second equation would show the total cost of the two type of fish:1.5y + 2x = 20

Respuesta:
$81.250.
Explicación paso a paso:
Datos dados
Principal = $ 65,000
Tasa = 5%
Tiempo = 5 años
La expresión de interés simple se da como
A = P (1 + rt)
Substiute
A = 65000 (1 + 0,05 * 5)
A = 65000 (1 + 0,25)
A = 65000 (1,25)
A = $ 81,250
Por lo tanto, la inversión después de 5 años es de $81,250
