The local appliance store is offering 15% off an entire purchase of $2,000 or more; or 30% off a single
item of $1,000 or more. use the prices listed above to determine which offer will save the most
money on these appliances?

The offer of 30% off a single item of $ 1000 or more will save most money on these appliances .

Step-by-step explanation:

Given as :

The purchase price = $ 2000

The offering discount = 15 %

Let The price of item after discount = x

So , x = ( $ 2000 ) - ( $ 2000 × 15 % )

Or,  x = ( $ 2000 ) - ( $ 2000 × 0.15 )

Or,  x = ( $ 2000 ) - ( $ 300 )

∴     x =  $ 1700

Now, Again

The purchase price = $ 1000

The offering discount = 30 %

Let The price of item after discount = y

So , y = ( $ 1000 ) - ( $ 1000 × 30 % )

Or,  y = ( $ 1000 ) - ( $ 1000 × 0.3 )

Or,  y = ( $ 1000 ) - ( $ 300 )

∴     y =  $ 700

Now, If we purchase two item at the cost price of $ 700 each , then it will cost as $ 700 × 2 = $ 1400

And for the same number of items at the cost price is $ 1700 after 15 % discount on list price of $ 2000 , So the second offer will save most .

Hence The offer of 30% off a single item of $ 1000 or more will save most money on these appliances . Answer

step-by-step explanation:

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
