Answer:
3) y = 2
Step-by-step explanation:
Step : 1
given 2 y-1 =3
Adding '1 ' on both sides, we get
2 y -1 +1 = 3+1
2 y = 4
dividing by '2' on both sides, we get

cancelling '2' on both sides, we get
y = 2
Original price of the radio is $64.30
Sale price - $51.44
Discount rate - 20%
This means that $51.44 is the discounted price or is equivalent to 80% of the original price, since the 20% equivalent is deducted from the original price.
To get the original price, divide $51.44 by its corresponding percentage, 80%.
$51.44 / 80% = $64.30
To get the discount, multiply the original price by its discount rate
$64.30 x 20% = $12.86
To get the sales price, deduct the discount from the original price.
$64.30 - $12.86 = $51.44
100% - 20% = 80%
