Marcus borrowed 13.45 on Thursday. He earned 45.32 on Friday and immediately

I'm not exactly sure what your asking, but throughout two days Marcus borrowed $13.45 and then made $45.32. If he immediately paid his owed money back then he would have a current amount of 31.87 in his possession. That is unless he had interest on that owed money for one day

Step-by-step explanation:

$45.32-$13.45 = $31.87

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!
