Given data

Initial cost= $9

final cost= $7.56

Required

The percent discount

Step two

Percent discount= final-initial/initial *100

Percent discount= 9-7.56/9 *100

Percent discount=1.44/9 *100

Percent discount=0.16 *100

Percent discount=16%

Hence the percent discount is 16%

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
