Answer:
$43.20
Step-by-step explanation:
To find the original purchase price, write a proportion and solve. A proportion is an equation where two ratios are set equal.
If the discount if 15% then you pay 85%.
To solve for y, cross multiply the numerator and denominator of each fraction.
36.72(100) = 85y
3672= 85y
43.2 = y
4x+4y=12
(-4y) (-4y)
4x= 12-4y
Divide 4
12-4y/4= x
I really hope it makes sense
10^6/10² = 10³
10^(6 - 2) = 10³
10^4 = 10³
10000 = 1000
this is false because both sides are not equal to each other which is not a solution.
hope this helps, God bless!
