Question

. What is the discount on $640 if the discount rates are 25%, 10%, and 5%?

Answer 1

Explanation:

25%: 640 X .25 =160

640-160= $480

10%: 640 X .10= 64

640- 64= $576

5%: 640 X .05 =32

640- 32= $608

Answer 2

the discount with rate 25%=$160,the discount with rate 10%=$64,the discount with rate 5%=$32

Explanation:

Hello, I think I can help you with this

the discount is a percentage, a proportion of the real value, we can find that proportion using a simple rule of three

let

100% =$640

Step 1

If

$640= 100%

x? % = 25%

($640/100%)=(x/25%)

isolating x

x=($640*25%)/(100%)

x=$160

the discount with rate 25%=$160

Step2

If

$640= 100%

x? % = 10%

($640/100%)=(x/10%)

isolating x

x=($640*10%)/(100%)

x=$64

the discount with rate 10%=$64

Step 3

If

$640= 100%

x? % = 5%

($640/100%)=(x/5%)

isolating x

x=($640*5%)/(100%)

x=$32

the discount with rate 5%=$32
