Show the answer
Correct answer: C
Set up proportions to figure out how many slides Deion and Kyra can create in 1 hour:
Deion
Deion can create 15 slides in 1 hour.
Kyra
Kyra can create 18 slides in 1 hour.
Add Deion and Kyra to figure out how many slides they can create together in 1 hour:
15 + 18 = 33.
