A clothing store offers customers a holiday sale of 20% off the price of x items. A customer then has an additional 15% off coupon that can be used when checking out. Which of the following functions represents the final price P(x) of the items purchased? P(x) = 0.68x
P(x) = 0.35x
P(x) = 0.05x
P(x) = 0.03x

Step-by-step explanation:

Original price = x

Sale price  = 20% off:

Further discount 15% off:

The function is:

Correct choice is A

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
