The Jocelyn needs to pay $87.5 if Jocelyn order cakes from store B if store A charges $1.50 per serving plus a $25.00 delivery charge. Store B charges $2.25 per serving and no delivery charge.
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the total cost is $x if Jocelyn purchase cake from store A:
x = 1.50×150 + 25
x = 225+25 = $250
Let's suppose the total cost is $y if Jocelyn purchase cake from store B:
y = 2.25×150
y = $337.5
Difference between total cost = 337.5 – 250 = $87.5
Thus, the Jocelyn needs to pay $87.5 if Jocelyn order cakes from store B if store A charges $1.50 per serving plus a $25.00 delivery charge. Store B charges $2.25 per serving and no delivery charge.
