For Jayden's lemonade recipe, 3 lemons are required to make 12 cups of lemonade. At what rate are lemons being used in lemons per cup of lemonade?

0.4 of lemon is being used for one cup

Step-by-step explanation:

12 divided by 3 is 4 which is more than 3 meaning we need to try and make it smaller which is why the 4 was carried down by one row making 0.4

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!
