Answer:
Betty produced 613 gallons while Georgette produced 851 gallons
Step-by-step explanation:
Let Betty be X and Georgette be Y
The first equation
Y= 2x-375
Second equation
X+Y = 1464
This is simultaneous equation.
We are using substitution method
From equation 1 the value of Y= 2x-375
Substitute for the value of y in equation 2
X+Y= 1464
X + 2X - 375= 1464
Collect like terms
3x=1464+375
3x= 1839
X= 613
To get the value of Y
Substitute for Y in equation 1
Y= 2x - 375
Y= 2(613) - 375
Y= 1226 - 375
Y= 851
Since X= Betty and Y = Georgette
Betty produced 613 gallons while Georgette produced 851 gallons
