Answer: [tex]3(0.28)+0.38 y[/tex] OR [tex]0.84+0.38y[/tex]
Step-by-step explanation:
Given : Jonathan goes to the store and purchases 3 pencils for $0.28 each, and y number of erasers for $0.38 each.
No. of pencils bough = 3
Rate of each pencil = $0.28
Then , Money( in dollars) spent on pencils = No. of pencils x rate of each pencil.
[tex]3\times0.28[/tex]
Also, No. of erasers = y
Rate of each eraser = $0.38
Then , Money( in dollars) spent on erasers = No. of erasers x rate of each pencil.
[tex]y\times0.38=0.38y[/tex]
Then , the expression that shows how much Jonathan spent ( in dollars)=
Money spent on pencils+Money spent on erasers
= 3(0.28)+0.38 y
= 0.84+0.38y
Hence , the required expression : [tex]3(0.28)+0.38 y[/tex] OR [tex]0.84+0.38y[/tex]
