Answer: OR
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.
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.
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 : OR
