Bill wanted to make a cake, and he wanted it to be a multilayer cake. So he used a scale factor to scale his recipe up to make all the batter at once, and he organized it into this table:
Ingredient
Cocoa
Eggs
Flour
Sugar
Butter
Single Layer
13 cup
2
Bill's Measurements
1 cup
16
4 1/2 cups
3 cups
4 1/2 sticks
1 1/2 cups
1 cup
1 12 sticks
How many layers will Bill's cake be?
No

Bill's cake will be three layers because as we take a look at the direction everything that is on bills is 3x the needed amount for the cake that holds one layer.

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!
