Question

Jonathan goes to the store and purchases 3 pencils for $0.28 each, and y number of erasers for $0.38 each. Write an expression that shows how much jonathan spent.

Answer 1

you do 3×0.28+y × 0.38

Answer 2

Answer:
`3(0.28)+0.38 y` OR
`0.84+0.38y`

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.

`3*0.28`

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.

`y*0.38=0.38y`

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 :
`3(0.28)+0.38 y` OR
`0.84+0.38y`
