Answer:
$24.08
Step-by-step explanation:
Step one:
given data
A store purchased a DVD for $15.00 and sold it to a customer for 50% more than the purchase price.
The increase is
=50/100*15
=0.5*15
=$7.5
Selling price
= 7.5+15
= $22.5
The tax is 7%
=7/100*22.5
=0.07*22.5
=1.575
The total cost/ amount paid is
1.575+22.5
=$24.075
=$24.08
Fist one:
x−2=−3
Second one: a=63b/23
Third one: x=−a/2+3b/2
70%
r=4 d=8 a = 16π c = 8π
d=6 r=3 a=9π c=6π
a=36π r=6 d=12 c=12π
c=18π r=9 d=18 a=81π
hope this helps (:
