Answer:
B
Step-by-step explanation:
Distributing the right side, the equation becomes
6-x=16+4x
Add x to both sides and subract 16
5x=-10
Divide by 5
x=-2
$12.50
Set up a ratio.
If it was 12% off, you paid 88%.
So 88/100=11/x
Cross multiply and solve for x.
So x=1100/88=12.50
Answer:
The price of the cell phone without the coupon= $500
Step-by-step explanation:
Step 1: Express discounted amount
The discounted amount can be expressed as a function of the original cost of the phone as follows;
D=r×A
where;
D=discounted amount
r=coupon rate
A=original price of the cell phone before the coupon
In our case;
r=45%=45/100=0.45
A=a
replacing;
Discounted amount=(0.45×a)=0.45 a
Step 2: Amount she pays up
Amount she pays=Original cost of cell phone-discounted amount
where;
Amount she pays= $275
original cost of cell phone=a
discounted amount=0.45 a
replacing;
$275=a-0.45 a
0.55 a=275
a=275/0.55
a=500
The price of the cell phone without the coupon= $500
Answer:
Both parts are solved below:
Step-by-step explanation:
Given that:
Purchase price = 150
Part (A)
As the online trailer marks up 30% so the price would be:
= 150 + 30% of 150
=150 + 0.3(150)
= 150 + 45
Price online= $195
As the superstore marks up the price by 40% so the price would be:
= 150 + 40% of 150
=150 + 0.4(150)
= 150 + 60
Price at superstore = $210
------------------------------------------------------------------------
Part(B)
Difference = price at superstore - price online
difference = 210 - 195
difference = $15
Difference in markup = 40% - 30% = 10%
So 10% difference leads to the difference of $15 in price.
i hope it will help you!
