Are the following proportional yes or no.
Brums [2.3K]

Answer:

Monday: 4 hours = $36

Tuesday: 6 hours = $54

Wednesday: 5 hours = $45

His earnings are proportional because, for each hour, Richard earns $9. Using the formula y = kx, k (the constant) is always the same:

  • 36 = k × 4 (k = $9)
  • 54 = k × 6 (k = $9)
  • 45 = k × 5 (k = $9)

Hope this helps!
