A family spends 20% of its monthly income on fuel. If they spend $324 a month on fuel, which is their monthly income?
nasty-shy [4]

Your answer is $1620.

To solve this, first look at what we're given. $324 is spent a month on fuel, and fuel is 20% of their income. Therefore, $324 is 20% of the family's income per month.

Now, to solve this, we're looking for 100% of the family's income. 20% is 1/5 of 100%, so therefore $324 is 1/5 of the family's full income.

To get 100%, then multiply 20% by 5 to get 100%, and therefore multiply $324 by 5 to get the full income.

$324 * 5 = 1620, or your answer.

Good luck!

Kevin planted ome corn in the back yard and meaure it height regularly. Currently, the talk are 75 inche tall. That i 25% taller
Pavlova-9 [17]

The height of the tree was 56 inches.

We can calculate the percentage of a certain amount by :

Subtracting  New - Original / New multiplied by 100

this implies it will be

75 - x / 75 × 100 = 25 %

7500 - 100 x = 1875

this implies 7500 - 1875 = 100 x

5625 = 100 x

Thus , On dividing both sides by 100 we get

56.25 = x

Now on rounding off this number we will get

56 = x

Thus the original height of the corn plant was 56 inches

Lunna [17]
Hi! First, we multiply both sides by 5, -n/5*5=5*5=-n=25. Second, we divide both sides by -1, -n/-1=25/-1. Therefore, our answer is n=-25

Juan compró un led TV en cuotas que costó $ 76.000=. Si le falta pagar 3 cuotas y ya pagó $ 47.000, ¿Cuál es el valor de cada cu
Murrr4er [49]

Respuesta:

$ 9666. 67

Explicación paso a paso:

Costo de TV = $ 76,000

Número de cuotas = 3

Monto ya pagado = $ 47000

Amontof cada cuota fija = Cantidad que queda por pagar / 3

Cantidad que queda por pagar = Costo de TV - Cantidad ya pagada

Cantidad que queda por pagar = $ (76000 - 47000) = $ 29000

Monto de cada cuota fija = $ 29000/3 = $ 9666. 67
