The expression 1.22y is the amount spent by Jonathan.

Step-by-step explanation:

  • The cost per pencil = $0.28

∴ The total cost of 3 pencils = 0.28[tex]\times[/tex]3 = $0.84

  • The cost per eraser = $0.38

∴ The total cost of y erasers = 0.38[tex]\times[/tex]y = $0.38y

Jonathan spent = Total cost of pencil + total cost of eraser

⇒ 0.84 + 0.38y

⇒ 1.22y
