Garry is cooking for his friends he wants to buy some potatoes, which are priced at m dollars a pround. he has already spent b dollars on other ingredients the following expression represents the total amount of Money That Garry would spend after buying x pounds of potatoes

amount spent = y

pounds of potatoes = x

dollars per pound = m

other ingredients cost = b

y=mx+b

amount spent = m * x + b

Step-by-step explanation:

Let y be the amount of money gary will spend and wants by x amount of potatoes at a prices of m dollars and he has already spent b dollars.

Therefore: The total cost of potatoes that Gary wants to buy is

= x pounds of potatoes * m dollars per pound of potatoes

= mx dollars spent

he has spent b dollars on other ingredients and therefore the total amount that Gary has spent is

= mx + b

So y=mx+b
