Answer:
$46.20
Step-by-step explanation:
We can create a proportion to find the sale on the original price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. If the price is discounted by 30% then we pay 70% of the price.
We begin solving by cross multiplying numerator to denominator of each fraction.
The number of different groups can be found by finding 9C3 (Using combinations)
We will find combinations from n = 9 to r = 3
Therefore, 9C3 = 9!/6!*3! = (9*8*7*6!)/(6!*3*2)
= 3*4*7
= 84 ways.
