Ryan works at the car wash making $5. 30 per hour plus tips. Last week Ryan worked 32 hours and earned $403. How much in tips did Ryan make last week? a. $86. 40 b. $148. 00 c. $169. 60 d. $233. 40 Please select the best answer from the choices provided A B C D.

d. $233.40

Step-by-step explanation:

you solve this by first multiplying Ryan's hourly rate($5.30) by how many hours he worked last week(32 hours)

5.30*32=169.6

then you take that number and subtract it from how much he earned($403) and the resulting number will be what he made in tips

403-169.9=233.40

d. $233.40

Step-by-step explanation:

pay for 32 hours

= $5.30 × 32

= $169.60

tips = $403 - $169.60

= $233.40

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
