brand a: $1.25 for 10 ounces
brand b: $1.47 for 12 ounces
brand c: $1.68 for 14 ounces
brand d: $1.84 for 16 ounces

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!
