Answer:
$3003.2
Step-by-step explanation:
Step 1
Paso 1
Averiguamos cuánto era el 25% de sus ahorros.
Se nos dice en la pregunta que gastó el 33.3% en decoraciones para su nueva casa y si los adornos cuestan $ 250.00.
Esto significa
33.3 % × x = 250
33.3 x/ 100 = 250
Cruz multiplicar
33.3x = 250 × 100
x = 25.000 / 33.3
x = 750.75075075
Por lo tanto, la cantidad o el costo de los adornos = 33.3% del 25% de sus ahorros = $ 750.8
Paso 2
De la pregunta:
Un joven retira el 25% de sus ahorros y
Por lo tanto:
Sea y = monto total de sus ahorros
25/100 × y = $ 750.8
25y = 100 × 750.8.
y = 100 × 750.8 / 25
y = $ 3003.2
Por lo tanto, tenía $ 3003.2 en su cuenta.
Watch carefully:
A 'zero' of the function is a value of 'x' that makes the function zero.
2x - 10 = 0
Add 10 to each side:
2x = 10
Divide each side by 2 :
x = 5
f(5) = 0
