amount spent = y
pounds of potatoes = x
dollars per pound = m
other ingredients cost = b
y=mx+b
Answer:
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
