19. (No calculator allowed). If Jeremy purchased x t-shirts at $12 a piece, and y sweaters at $45 a piece,which expression represents the total value of the purchase?

Respuesta :

From the question;

Jeremy purchased x t-shirts at $12 a piece

This implies

Cost of x t-shirts = $12 times x

= $12x

Also

He purchased y sweaters at $45 a piece

This implies

Cost of y swearters = $45 times y

= $45y

Therefore

Total value of purchase = Cost of x t-shirts + Cost of y swearters

Hence

Total value of purchase = $12x + $45y
