Earl gets a commission of 20% on all sales. he sold $1,580.00 worth of goods. what was the amount of his paycheck?

For this case we can make the following rule of three:

100% -----------------> $ 1,580.00

20% -------------------> x

From here, we clear the value of x.

We have then:

From here, you get the amount that Earl earns in commissions.

the amount of his paycheck is $ 316

it should be a and d. lmk if i'm wrong xd

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!
