Answer:
$ 3,213.30
Step-by-step explanation:
2350(1.09)¹⁰ - 2350 = 3,213.30
This is a proportion so
6/15=2/c
make the left side top number equal to the right side top number and you will find c
6/15=2/c
6/3=2
6/15 times (1/3)/(1/3)=2/5
2/5=2/c
c=5
the other way is multiply both sides by c/2
6c/30=1
multiply both sides by 30
6c=30
divide both sides by 6
c=5
You can put 10 in the equation:
-10^2 -3*10 = -100 -30 = -130
Answer:
see below
Step-by-step explanation:
Let x be the original price
x* discount rate = discount
x * 60% = 30
Change to decimal form
x * .60 = 30
Divide each side by .60
x = 30/.60
x =50
The original price was 50 dollars
