Steve baked 55 batches of cookies in
one and one half hours. vondra baked 31
batches of cookies in 1 hour. which baker
made cookies at a greater rate of batches
per hour?

*answer this question by comparing unit rates

Basically, you need to divide these by the number of minutes it took to make them. So, for example:

Since one hour and a half equals 90 minutes, Steve baked cookies at a rate of 0.61111 (the one keeps repeating) per minute (55 divided by 90).

Since one hour equals 60 minutes, Vondra baked cookies at a rate of 0.516666 ( the six keeps repeating) per minute (31 divided by 60).

This means that Steve baked batches of cookies at a greater rate than Vondra.

step-by-step explanation:

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!
