First, you would multiply $210 by 20%
This is done by converting 20% to a decimal, .2

So, 210 • .2 = 42

Then to find the sale price, you would subtract that 42 that you just got from 210,

and you get $168 as the final sale price.

John’s father is 5 times older than John and John is twice as old as his sister Alice. In two years time, the sum of their ages
oksano4ka [1.4K]

Answer:

8 years

Step-by-step explanation:

Let age of father be f

age of John be j

age of Alice be a

John's father is 5 times as old as John. We can write:

f = 5j

John is twice as old as Alice. We can write:

j = 2a

or

a = j/2

SUM OF ALL OF THEIR AGES (after 2 years) will be 58. We can write:

f+2 + j+2 + a+2 = 58

This becomes:

f + j + a + 6 = 58

f + j + a = 52

Now, we replace third equation with the first two (in bold) and get:

f + j + a = 52\\5j + j + \frac{1}{2}j=52\\6.5j=52\\j=8

So John is 8 years old

Since you have to move the decimal point the the right by 7 places to get the decimal point after the one.  You must multiply by 1/10 seven times, which is the same as:

(-5)(2) – 2(-3) + 3

=-10-(-6)+3
